Diagram Ref No 13

The line forms part of the brake servo system, carrying vacuum to the brake booster so that additional assistance can be applied when the driver presses the brake pedal.

A properly sealed vacuum line is essential for maintaining effective brake assistance. If the original pipe becomes cracked, damaged or develops a leak, the brake booster may not receive sufficient vacuum, resulting in increased pedal effort and reduced braking assistance.

This genuine Porsche replacement restores the correct vacuum connection and factory routing within the braking system.

What This Product Does:
The brake booster, also known as the brake servo, uses vacuum assistance to reduce the amount of physical force required from the driver when applying the brakes.

The vacuum line provides the connection through which vacuum reaches the brake booster.

Its primary functions include:

• Supplying vacuum to the brake booster
• Maintaining a sealed vacuum circuit
• Supporting power-assisted braking
• Reducing the amount of pedal effort required during braking
• Helping provide consistent brake pedal assistance
• Maintaining the correct factory routing of the vacuum system
• Connecting the brake servo to the relevant vacuum supply components

The vacuum line does not create braking pressure itself. Instead, it allows the brake booster to assist the hydraulic braking system.

Symptoms Of Wear Or Failure:
Vacuum lines can deteriorate through age, engine-bay heat, vibration and repeated pressure changes.

Common symptoms of a damaged or leaking brake booster vacuum line include:

• Brake pedal becoming unusually hard
• Increased effort required to stop the vehicle
• Reduced brake servo assistance
• Brakes feeling normal initially but becoming harder after repeated applications
• Hissing or sucking noise when the brake pedal is pressed
• Audible vacuum leak from the engine compartment
• Cracks or splits in the vacuum pipe
• Damaged or loose connections
• Vacuum hose becoming brittle or hardened
• Physical damage to the line
• Brake booster performance becoming inconsistent
• Vacuum-related fault codes where monitored by the vehicle
• Poor sealing around vacuum-line connections

A hard brake pedal can also be caused by a faulty brake booster, vacuum pump, non-return valve or related vacuum-system component, so correct diagnosis is recommended before replacement.

Why Replacement Matters:
The brake booster significantly reduces the physical effort required to apply the brakes.

If the vacuum line leaks or becomes disconnected, the booster may not receive enough vacuum to provide normal assistance. The hydraulic braking system may still operate, but substantially more pedal force can be required from the driver.

This can make the vehicle more difficult to stop comfortably and predictably, particularly during emergency braking or repeated brake applications.

A vacuum leak can also prevent the brake servo from storing or maintaining sufficient vacuum between braking events.

Replacing a damaged vacuum line helps restore:

• Correct brake booster vacuum supply
• Normal power-assisted braking
• Consistent brake pedal effort
• Reliable brake servo operation
• Proper sealing of the vacuum circuit
• Factory-correct hose routing and connections

Because this component forms part of the braking assistance system, cracks, leaks or damaged connections should not be ignored.

Diagram Ref No 17

The hose forms part of the engine cooling circuit, carrying coolant between the expansion tank, radiator and associated coolant pipework. By providing a sealed return path, it helps maintain continuous coolant circulation and stable engine operating temperatures.

Manufactured to Porsche specifications, this replacement hose restores the original routing, connection points and cooling-system integrity when the existing hose has become cracked, hardened, swollen or is leaking.

What This Product Does:
The engine cooling system continuously circulates coolant to absorb heat from the engine and release it through the radiator.

The return hose forms part of this circulation loop and allows coolant to flow back through the system after passing through cooling-system components.

Its main functions include:

• Carrying coolant through the return side of the cooling circuit
• Maintaining continuous coolant circulation
• Helping maintain correct cooling-system pressure
• Supporting stable engine operating temperatures
• Providing a sealed connection between cooling-system components
• Helping prevent coolant loss
• Maintaining the original factory coolant routing
• Supporting efficient engine heat management

The hose itself does not cool the engine directly, but uninterrupted coolant flow through it is essential for the cooling system to work correctly.

Symptoms Of Wear Or Failure:
Coolant hoses are continually exposed to heat, pressure, vibration and chemical contact with engine coolant. Over time, the hose material and connections can deteriorate.

Common symptoms that may indicate replacement is required include:

• Visible coolant leaks
• Dampness around the hose or connections
• Pink, white or coloured coolant residue around joints
• Cracks or splits in the hose
• Swollen or bulging sections
• Hose becoming unusually soft or spongy
• Rubber becoming hard or brittle
• Low coolant warning message
• Repeated need to top up the coolant
• Sweet coolant smell from the engine bay
• Engine temperature running higher than normal
• Fluctuating coolant temperature
• Steam from the engine compartment in severe cases
• Damage or leakage around quick-connect fittings

A low coolant level or overheating can also result from leaks elsewhere in the cooling system, so the complete circuit should be inspected.

Why Replacement Matters:
The cooling system must remain sealed and properly pressurised to control engine temperature effectively.

If the coolant return hose develops a leak, coolant can escape and the system may gradually lose pressure. As the coolant level drops, the engine's ability to transfer and dissipate heat is reduced.

A small leak can quickly become more serious if an ageing hose splits under operating pressure.

Continued driving with insufficient coolant can cause:

• Engine overheating
• Cylinder-head or head-gasket damage
• Damage to seals and cooling-system components
• Reduced engine reliability
• Breakdown caused by sudden coolant loss

Replacing a deteriorated hose helps restore:

• Correct coolant circulation
• Proper cooling-system pressure
• A leak-free cooling circuit
• Stable engine temperature
• Reliable long-term cooling-system operation

Replacing the hose at the first signs of cracking, swelling or leakage can help prevent a relatively inexpensive hose fault from developing into a much more costly overheating problem.

Diagram Ref No 7

The assembly combines rigid hydraulic pipework with a flexible hose section, allowing clutch fluid pressure to be transferred through the vehicle while accommodating movement and vibration between components.

When the clutch pedal is pressed, hydraulic pressure generated by the clutch master cylinder is transmitted through the clutch line to the slave-cylinder side of the system. This allows the clutch mechanism to disengage so that gears can be selected smoothly.

What This Product Does:
The hydraulic clutch line forms a sealed pressure path within the clutch operating circuit.

Its main functions include:

• Carrying pressurised hydraulic fluid through the clutch system
• Transferring clutch-pedal input to the clutch release mechanism
• Supporting smooth clutch engagement and disengagement
• Allowing the clutch to fully disengage during gear changes
• Maintaining hydraulic pressure within the clutch circuit
• Accommodating drivetrain movement through its flexible hose section
• Preventing hydraulic fluid loss when the system is correctly sealed
• Maintaining the original Porsche hydraulic clutch layout

Correct operation of this line is essential for consistent clutch-pedal feel and reliable manual gear selection.

Symptoms Of Wear Or Failure:
A hydraulic clutch tube or hose can deteriorate through heat, age, vibration, corrosion or physical damage.

Possible symptoms include:

• Hydraulic fluid leaking from the clutch line
• Dampness around pipe or hose connections
• Visible fluid residue on the line
• Cracked or deteriorated flexible hose material
• Corrosion on rigid pipe sections
• Damaged or kinked pipework
• Bulging hose sections
• Loose or damaged fittings
• Soft or spongy clutch pedal
• Clutch pedal travelling farther than normal
• Clutch pedal slowly sinking
• Clutch pedal failing to return correctly
• Difficulty selecting gears
• Difficulty engaging first or reverse gear
• Gear grinding during selection
• Clutch dragging when the pedal is fully depressed
• Changing clutch engagement point
• Loss of clutch hydraulic pressure

A soft clutch pedal can also result from a failing master cylinder, slave cylinder or air elsewhere in the hydraulic circuit, so the complete system should be inspected.

Why Replacement Matters:
A damaged clutch line can lead to progressive pressure loss and eventually prevent the clutch from disengaging.

Continued use with a deteriorating line can result in:

• Increasing difficulty changing gear
• Clutch drag
• Gear grinding
• Increased wear on gearbox synchronisers
• Loss of clutch-pedal function
• Complete hydraulic failure
• Vehicle becoming difficult or impossible to drive
• Unexpected breakdown

Replacing a leaking or damaged hydraulic line restores the sealed pressure path required for correct clutch operation.

Breather Line.

The Porsche Breather Line 9GT301047A is a genuine Porsche replacement ventilation line used within the PDK transmission and clutch breather system on selected Porsche 911 GT3 applications.

Fits:

• Porsche 992.1 GT3 4.0L / 992 S/T 4.0L 2021-24
• Porsche 992.1 GT3 RS 4.0L 2022-24  

Diagram Ref No 34

The line forms part of the gearbox ventilation arrangement, providing a controlled route for pressure equalisation as the transmission and clutch assembly heat up and cool down during operation.

Porsche catalogues the part for the 7-speed PDK transmission code CBG.91, where it is fitted as a single breather line within the transmission assembly.

Manufactured as a genuine Porsche component, it provides the correct dimensions, connections and routing for the original installation.

What This Product Does:
During operation, transmission components and lubricants become hot.

As temperature increases, the air and vapour inside the transmission housing expand. A properly functioning breather system allows these pressure changes to be managed without excessive internal pressure building inside the gearbox.

The breather line helps:

• Vent the PDK transmission and clutch housing correctly
• Allow internal pressure to equalise as temperatures change
• Route gearbox vapour through the intended ventilation path
• Prevent excessive pressure building inside the transmission
• Support correct operation of gearbox seals and gaskets
• Reduce the likelihood of oil being forced past sealing surfaces
• Maintain the original Porsche gearbox ventilation arrangement

Although it does not directly control gear selection or clutch engagement, it supports the environment in which these components operate.

Symptoms Of Wear Or Failure:
Breather lines can deteriorate through heat, vibration, age or physical damage.

Possible symptoms include:

• Visible cracking or splitting
• Hardened or brittle hose material
• Kinked or crushed tubing
• Loose connections
• Line becoming detached
• Oil mist around the breather connection
• Transmission oil residue around the gearbox
• Dampness around adjacent fittings
• Unusual oil seepage from gearbox seals
• Repeated transmission oil leaks with no obvious seal failure
• Contamination or debris blocking the breather line
• Damaged retaining clips or supports

Because this is a passive ventilation component, a failed line may not immediately trigger a dashboard warning.

Why Replacement Matters:
A damaged, disconnected or blocked breather line can interfere with the transmission's ability to manage internal pressure.

Continued operation with a defective breather may contribute to:

• Increased gearbox oil leakage
• Additional stress on transmission seals
• Oil contamination around surrounding components
• Loss of transmission lubricant
• Dirt or moisture entering the breather system
• Premature deterioration of associated seals
• Increased maintenance requirements

Replacing a failed line restores the intended ventilation route and helps maintain the transmission's designed operating environment.

Diagram Ref No 48

The hose forms part of the engine oil circulation and cooling system, providing a secure route for engine oil between associated pipes and oil-system components.

Because the air-cooled Porsche 993 relies heavily on engine oil for both lubrication and heat management, maintaining leak-free oil hoses is especially important.

This genuine Porsche replacement is suitable for renewing an original hose that has become hardened, cracked, oil-soaked, damaged or is beginning to leak.

What This Product Does:
Engine oil performs several critical functions within the Porsche 993, including lubrication, cleaning and heat removal.

The oil hose forms part of the circuit that allows oil to circulate between the engine and associated oil-system components.

Its main functions include:

• Carrying engine oil through the lubrication and cooling circuit
• Maintaining a sealed oil connection
• Supporting reliable engine oil circulation
• Helping maintain correct oil pressure and flow
• Supporting engine lubrication
• Helping transfer heat away from internal engine components
• Preventing oil loss when correctly sealed
• Maintaining the original factory oil-system routing

The hose itself does not generate oil pressure, but it must remain unrestricted and leak-free for the oil system to operate correctly.

Symptoms Of Wear Or Failure:
Oil hoses deteriorate over time due to heat, oil exposure, vibration and repeated thermal cycling.

Common signs that replacement may be required include:

• Visible engine oil leakage
• Wet or oily deposits around the hose
• Oil seepage around hose connections
• Cracks or splits in the hose material
• Rubber becoming hard or brittle
• Hose becoming swollen or unusually soft
• Deterioration of the outer surface
• Corroded or damaged hose fittings
• Falling engine oil level
• Oil stains beneath the vehicle
• Burning-oil smell after driving
• Smoke if leaking oil reaches hot exhaust components
• Oil contamination around surrounding engine components

A falling oil level can also originate elsewhere in the engine, so the complete lubrication system should be inspected when a leak is found.

Why Replacement Matters:
Reliable oil circulation is essential to the longevity of the Porsche 993's air-cooled engine.

If an oil hose begins to leak, the engine can gradually lose oil. Even a relatively small leak may eventually reduce the oil level enough to compromise lubrication and cooling.

More significant oil loss can contribute to:

• Reduced engine lubrication
• Increased friction and wear
• Higher operating temperatures
• Reduced oil pressure
• Bearing or internal engine damage
• Breakdown caused by severe oil loss

Leaking oil may also reach hot exhaust or engine components, producing smoke and creating an increased fire risk.

Replacing a deteriorated oil hose helps restore:

• A sealed engine oil circuit
• Reliable oil circulation
• Correct oil-system integrity
• Reduced risk of oil loss
• Effective engine lubrication
• Reliable heat management

On an air-cooled Porsche, maintaining the oil circuit is particularly important because engine oil plays a major role in controlling operating temperature as well as lubricating internal components.

Automatic Transmission Oil Cooler.

The Porsche Automatic Transmission Oil Cooler 95530701701 is a genuine replacement gearbox oil cooler designed to help regulate automatic transmission fluid temperature on Porsche Cayenne applications.

Fits:

• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10

Diagram Ref No 1

The cooler forms part of the Tiptronic transmission cooling system. As automatic transmission fluid circulates through the gearbox, it absorbs heat generated by the torque converter, internal clutches, gears and hydraulic system. The oil cooler removes excess heat from the fluid before it returns to the transmission.

Maintaining the correct ATF temperature is essential for reliable shifting, effective lubrication and long-term transmission durability.

This genuine Porsche replacement is suitable for replacing an original cooler that has become damaged, corroded, restricted or is leaking.

What This Product Does:
Automatic transmission fluid performs several important functions inside the gearbox, including lubrication, hydraulic control, cooling and transmitting force through the torque converter.

During normal driving, and particularly under heavy load, the transmission can generate considerable heat. The transmission oil cooler helps dissipate this heat and keep the ATF within its intended operating temperature range.

Its functions include:

• Cooling automatic transmission fluid
• Removing excess heat generated by the gearbox and torque converter
• Helping maintain a stable transmission operating temperature
• Protecting transmission fluid from excessive thermal degradation
• Supporting consistent hydraulic pressure and gear changes
• Helping protect internal transmission components
• Supporting reliable transmission performance under demanding conditions
• Maintaining efficient circulation through the transmission cooling circuit

The cooler itself does not control gear selection, but correct transmission temperature is important for proper operation of the complete Tiptronic system.

Symptoms Of Wear Or Failure:
Transmission oil coolers can deteriorate because of age, corrosion, impact damage, blocked cooling fins or internal restriction.

Common symptoms that may indicate a faulty or deteriorating transmission oil cooler include:

• Automatic transmission running hotter than normal
• Transmission overheating warnings
• Gear changes becoming harsh or inconsistent when hot
• Delayed engagement of Drive or Reverse
• Transmission performance deteriorating after prolonged driving
• ATF leaking from the cooler or connections
• Red or brown fluid visible beneath the vehicle
• Oily residue around the cooler or transmission cooling lines
• Visible corrosion on the cooler
• Bent or damaged cooling fins
• Physical impact damage
• Restricted airflow through heavily contaminated fins
• Darkened or burnt-smelling transmission fluid
• Transmission entering a protective or reduced-performance mode

Similar symptoms can be caused by low ATF level, damaged cooler pipes, thermostat problems or internal gearbox faults, so the complete transmission cooling circuit should be inspected before replacement.

Why Replacement Matters:

• Automatic transmissions are highly sensitive to excessive operating temperatures. If the oil cooler becomes blocked, damaged or inefficient, the transmission fluid may operate at higher temperatures than intended.
• Excessive heat accelerates ATF degradation and reduces its ability to lubricate, cool and operate the gearbox's hydraulic components effectively. Over time, this can contribute to increased wear of seals, clutches, bearings and other internal transmission components.
• A leaking cooler can also cause the ATF level to fall. Insufficient transmission fluid can lead to poor lubrication, hydraulic pressure problems, abnormal shifting and potentially serious gearbox damage.
• Replacing a damaged or restricted cooler helps restore effective heat dissipation and allows the transmission to operate within its intended temperature range. It can also help protect a considerably more expensive gearbox from damage caused by prolonged overheating or low fluid levels.
• Whenever the cooler is replaced, the associated transmission cooler lines, connections, seals and ATF condition should also be inspected.

• Porsche 970.2 Panamera Diesel V6 3.0L (250Hp) 2014-16  

Diagram Ref No 19

Positioned at the visible end of the exhaust system, the tailpipe provides the final outlet for exhaust gases while completing the factory appearance of the rear exhaust assembly.

Designed to Porsche specifications, this replacement restores the correct fit, positioning and appearance when the original tailpipe has become scratched, corroded, dented, discoloured or damaged.

What This Product Does:
The tailpipe forms the final visible section of the exhaust system through which exhaust gases leave the vehicle.

Its main functions include:

• Directing exhaust gases away from the rear of the vehicle
• Providing the finished outlet for the exhaust system
• Maintaining correct alignment within the rear bumper opening
• Completing the original factory exhaust appearance
• Providing a secure connection to the rear exhaust assembly
• Helping prevent unwanted movement or vibration
• Maintaining suitable clearance from the surrounding bumper and trim

The tailpipe itself is primarily a finishing and outlet component rather than a performance modification, but correct fitment is important for alignment, appearance and secure exhaust operation.

Symptoms Of Wear Or Failure:
Exhaust tailpipes are continuously exposed to heat, condensation, exhaust deposits and road contamination.

Common signs that replacement may be required include:

• Surface corrosion or rust
• Pitting or deterioration of the finish
• Permanent staining or heat discolouration
• Heavy soot accumulation
• Scratches or cosmetic damage
• Dents or deformation
• Loose mounting points
• Rattling or vibration while driving
• Poor alignment within the bumper opening
• Cracks around joints or attachment areas
• Exhaust leakage around the connection
• Tailpipe contacting the bumper or surrounding trim
• Significant visual difference compared with the opposite-side tailpipe

Severe corrosion or physical damage can weaken the mounting area and eventually allow the tailpipe to become loose.

Why Replacement Matters:
The exhaust tailpipe is one of the most visible components at the rear of the Porsche Panamera, so corrosion or damage can noticeably affect the appearance of the vehicle.

More importantly, a loose or distorted tailpipe may move excessively and contact the surrounding bumper or trim.

Continued movement can lead to:

• Rattling and vibration
• Damage to surrounding bodywork or trim
• Poor exhaust outlet alignment
• Increased stress on clamps and mounting hardware
• Exhaust leakage around the connection
• Further deterioration of the exhaust outlet
• Replacing a damaged tailpipe helps restore:
• Correct exhaust outlet positioning
• Secure mounting
• Factory-style appearance
• Proper clearance from surrounding trim
• Reduced unwanted vibration or rattling
• A clean and complete exhaust finish

Where the remainder of the exhaust system is still in good condition, replacing only the damaged tailpipe provides a practical alternative to replacing the rear silencer or complete exhaust assembly.

Suspension noise does not necessarily indicate a defective bar. Worn bushes, coupling rods, brackets or fasteners are more frequent causes, so the complete stabiliser assembly should be inspected before parts are replaced.

Why Replacement Matters

A bent, damaged or incorrectly specified stabiliser can change the suspension characteristics intended for the car. Installing the correct PR-code-specific Porsche part helps retain the original rear chassis configuration. Inspect the associated bushes, clamps, brackets, links and fixings while access is available.

FAQs

• How is the correct anti-roll bar identified?
  Compare part number 98133370314 and the listed PR codes with the vehicle VIN and factory equipment data.
• Is the anti-roll bar always responsible for rear suspension knocks?
  No. Check the bushes, coupling rods, brackets and mounting hardware first, as wear in these components commonly causes noise.
• Are bushes, brackets and coupling rods included?
  These are separate parts within the stabiliser assembly and should be assessed individually.

The feed line forms part of the hydraulic clutch system and supplies brake/clutch fluid to the clutch master cylinder. This allows the master cylinder to generate hydraulic pressure when the clutch pedal is pressed, ultimately operating the clutch release mechanism.

Designed to follow the original Porsche routing and connection arrangement, this genuine replacement is suitable for renewing a feed line that has become brittle, cracked, damaged or is leaking with age.

What This Product Does:
The hydraulic clutch system relies on a continuous supply of fluid to operate correctly.

The feed line connects the fluid supply to the clutch master cylinder. When the clutch pedal is depressed, the master cylinder uses this fluid to create hydraulic pressure, which is then transferred through the pressure line to the clutch slave cylinder and release mechanism.

Its main functions include:

• Supplying hydraulic fluid to the clutch master cylinder
• Maintaining a sealed fluid connection
• Ensuring the master cylinder has an uninterrupted fluid supply
• Supporting smooth clutch engagement and disengagement
• Helping maintain consistent clutch pedal operation
• Supporting reliable gear changes
• Maintaining the factory hydraulic-line routing
• Helping prevent fluid loss and air entering the clutch system

Unlike the high-pressure clutch pipeline, this component primarily serves as the feed or supply line to the master cylinder.

Symptoms Of Wear Or Failure:
Age, heat and prolonged exposure to hydraulic fluid can cause the original feed line to deteriorate.

Common symptoms that may indicate replacement is required include:

• Visible hydraulic fluid leakage
• Dampness around the feed line or its connections
• Cracks or splits in the line
• Hardened or brittle hose material
• Swelling or deformation
• Fluid level gradually falling
• Soft or spongy clutch pedal
• Inconsistent clutch pedal feel
• Clutch pedal failing to return normally
• Difficulty disengaging the clutch
• Difficulty selecting gears
• Air entering the clutch hydraulic system
• Fluid contamination around the clutch master cylinder

A soft clutch pedal or poor disengagement can also be caused by a worn master cylinder, slave cylinder, pressure line or air elsewhere in the hydraulic circuit, so the complete system should be inspected.

Why Replacement Matters:
The clutch master cylinder requires a reliable supply of hydraulic fluid to operate correctly.

If the feed line cracks or leaks, fluid can escape and air may enter the system. This can prevent the master cylinder from generating consistent hydraulic pressure and may lead to a soft pedal, incomplete clutch disengagement or difficulty selecting gears.

Continued fluid loss can eventually result in complete loss of hydraulic clutch operation, leaving the clutch unable to disengage.

Replacing a deteriorated feed line helps restore:

• A reliable hydraulic fluid supply
• Correct clutch master cylinder operation
• Consistent clutch pedal feel
• Smooth clutch disengagement
• Easier and more predictable gear selection
• Proper sealing of the clutch hydraulic circuit
• Correct factory line routing

Replacing a visibly aged or leaking line can also help prevent more disruptive clutch hydraulic failure later.

• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10  

Cars With Option Codes:
9AH - 4-Zone Air Conditioning System

Diagram Ref No 1

Located within the rear A/C refrigerant circuit, this pressure line carries pressurised refrigerant between components of the climate-control system. Correct refrigerant circulation is essential for the air-conditioning system to remove heat from the cabin and provide effective cooling.

As an original Porsche replacement component, the line is intended to restore the correct routing, sealing and pressure integrity of the factory air-conditioning system when the existing pipe has become corroded, damaged or has developed a refrigerant leak.

What This Product Does:
The air-conditioning system operates by continuously circulating refrigerant through a closed circuit containing the compressor, condenser, expansion components and evaporator.

This pressure line forms part of that sealed refrigerant circuit and transports refrigerant under pressure to the appropriate A/C components.

Its functions include:

• Carrying pressurised A/C refrigerant through the system
• Maintaining a sealed refrigerant circuit
• Supporting correct operation of the rear air-conditioning system
• Helping maintain the required refrigerant pressure
• Allowing efficient heat transfer and cabin cooling
• Maintaining the original factory refrigerant routing
• Providing a secure connection between A/C components

If the line cannot maintain a proper seal, refrigerant can escape and air-conditioning performance will progressively deteriorate.

Symptoms Of Wear Or Failure:
A/C refrigerant lines can deteriorate because of corrosion, vibration, road debris, repeated heat cycles or damage to connections and seals.

Common symptoms of a failing pressure line include:

• Air-conditioning no longer blowing cold air
• Reduced or inconsistent cooling performance
• Rear A/C noticeably warmer than expected
• Refrigerant level repeatedly becoming low
• A/C requiring frequent recharging
• Visible corrosion on the refrigerant pipe
• Cracks, dents or physical damage to the line
• Oily residue around the pipe or connection points
• Refrigerant dye visible around a leaking joint
• Hissing from the A/C system after shutdown
• Compressor cycling on and off more frequently than normal
• A/C system refusing to engage because refrigerant pressure is too low
• Loss of cooling shortly after the system has been recharged

An oily deposit is a common visual indication of leakage because small quantities of compressor oil circulate with the refrigerant and may escape with it.

Why Replacement Matters:

• The air-conditioning system must remain sealed to operate correctly. Even a small leak in a pressure line allows refrigerant to escape, gradually reducing the system's ability to cool the cabin.
• Operating the system with insufficient refrigerant can also reduce lubrication circulation through the compressor. If refrigerant loss is ignored for an extended period, this can contribute to more expensive A/C system problems.
• Replacing a leaking or corroded pressure line helps restore the sealed refrigerant circuit and enables the system to be correctly evacuated, leak-tested and recharged to the specified refrigerant quantity.
• Replacement is particularly important where corrosion has weakened the pipe, as a minor leak can eventually develop into a more substantial failure and lead to complete loss of air-conditioning performance.
• Because the A/C system contains refrigerant under pressure, servicing and recharging should be carried out using appropriate refrigerant recovery and charging equipment.

Small leaks may only appear when the engine is fully warm and the cooling system has reached operating pressure.

Why Replacement Matters:
A leaking coolant supply pipe can reduce both coolant quantity and system pressure.

As coolant is lost, air may enter the system and circulation can become less effective.

Continued operation with a damaged pipe can contribute to:

• Loss of coolant
• Reduced cooling efficiency
• Cooling-system pressure loss
• Air pockets within the system
• Localised hot spots
• Engine overheating
• Reduced heater performance
• Coolant warning messages
• Roadside breakdown
• Serious engine damage if overheating becomes severe

Replacing a deteriorated tunnel pipe restores the integrity of the coolant circuit and helps maintain reliable temperature control.

Diagram Ref No 1

The pressure line carries hydraulic fluid under pressure through the power steering system, helping transfer hydraulic assistance to the steering rack when the steering wheel is turned.

Because the line operates under significant hydraulic pressure, secure fittings and leak-free pipework are essential. This genuine Porsche replacement is suitable for renewing an original pressure line that has become corroded, damaged, cracked or is leaking.

What This Product Does:
The hydraulic power steering system reduces the physical effort required to turn the front wheels.

The power steering pump circulates hydraulic fluid under pressure, while the pressure line carries this fluid towards the steering gear where hydraulic assistance is applied.

Its main functions include:

• Carrying pressurised power steering fluid
• Supplying hydraulic pressure to the steering system
• Supporting power-assisted steering operation
• Helping reduce steering effort
• Maintaining a sealed hydraulic circuit
• Supporting smooth and consistent steering response
• Maintaining the correct factory routing between steering components
• Preventing hydraulic fluid loss when correctly sealed

The pressure line itself does not generate hydraulic pressure; it safely transfers the pressure produced by the power steering pump.

Symptoms Of Wear Or Failure:
Power steering lines are exposed to hydraulic pressure, engine and road heat, vibration, moisture and ageing.

Common symptoms of a failing pressure line include:

• Visible power steering fluid leakage
• Wet or oily deposits around the line
• Leakage around unions or fittings
• Falling power steering fluid level
• Fluid stains beneath the vehicle
• Steering becoming heavier than normal
• Intermittent loss of steering assistance
• Whining or groaning from the power steering pump
• Noise when turning the steering wheel
• Foaming or aeration in the power steering fluid
• Cracked or deteriorated flexible hose sections
• Corrosion on metal pipe sections
• Damaged or distorted pipework
• Burning-fluid smell if leaked fluid reaches hot components

Heavy steering or pump noise can also be caused by a failing pump, steering rack or other hydraulic lines, so the complete system should be inspected before replacement.

Why Replacement Matters:
The power steering pressure line must contain hydraulic fluid at substantial operating pressure.

If the line develops a leak, the fluid level can gradually fall and hydraulic assistance may become weaker or inconsistent. A significant leak can eventually result in a noticeable increase in steering effort.

Continued operation with insufficient power steering fluid can also cause the pump to run without adequate lubrication and cooling, potentially resulting in expensive pump damage.

A deteriorated pressure line can also fail suddenly, causing rapid fluid loss.

Replacing a leaking or damaged pressure line helps restore:

• Correct hydraulic pressure
• Reliable power-assisted steering
• Consistent steering effort
• A sealed power steering circuit
• Correct fluid circulation
• Protection of the power steering pump and steering rack
• Factory-correct line routing and connections

Addressing a small leak early can therefore help prevent damage to more expensive steering components.
