Diagram Ref No 12

What This Product Does:

• This mirror cover trim functions as the external finishing piece on the door mirror assembly: it fits around the mirror base or where the mirror connects to the door, covering the internal mounting points, wiring harness, adjustment motor housing, and provides a seamless external appearance.
  
• Because the mirror is electrically adjustable, this cover helps protect the delicate mirror motor/wiring assembly from water ingress, debris, vibration and ensures the wiring routing remains hidden and clean.
• It also helps retain aerodynamic and stylistic integrity: the correct trim ensures the mirror assembly looks as the manufacturer intended, aligning flush with the door panel, matching paint or trim finish and preventing wind-noise or water leaks at the mirror mount.

Signs You Might Need Replacement:

• The mirror cover trim is cracked, damaged or broken, which may expose wiring or internal mirror mount components.
  
• The cover is missing entirely, or was removed and not replaced during a mirror repair or door panel replacement.
  
• The exterior appearance looks unfinished, misaligned or the mirror base contains visible mounting hardware — indicating the trim cover is absent or incorrectly fitted.
  
• You’re restoring the vehicle to high appearance standards and want the correct OEM cover replacing an old/preserved piece that has aged, faded, scratched or lost its fit.

Why Replacement Matters:

• Appearance & finish: As a visible part of the door mirror assembly, the trim cover impacts the overall exterior look of the vehicle. A proper fit and finish is important for premium vehicles like the relevant Porsche models.
  
• Protection & durability: The cover helps shield the mirror motor, wiring and mounts from the elements (rain, debris, vibration). Without a proper cover, wires may be exposed, and water ingress could lead to mirror motor failure or corrosion.
  
• Restoration/value maintenance: For a high-value vehicle, having correct OEM exterior trims (mirror cover, painted or unpainted) contributes to authenticity, build quality and resale value.
  
• Completes mirror assembly: When replacing the mirror or servicing the door panel, the cover is often overlooked; replacing it ensures the job is truly finished and the mirror assembly returns to factory specification.

Breather Line.
Renew the ventilation path on your Porsche 911 (996-series) with these genuine breather / vent hoses. Designed for 1998-2005 911 (996) models (including Carrera, Turbo variants) these hoses ensure your engine’s breather or cooling-vent line operates correctly—preventing vapour or pressure buildup, supporting correct engine ventilation and maintaining system reliability.

Fits:

• Porsche 996 C2 3.4L 1997-08/01
• Porsche 996 C4 3.4L 1997-08/01
• Porsche 996 C2 3.6L 09/01-2005

• Porsche 996 C4S 3.6L 09/01-2005
• Porsche 996 TURBO 2000-05

Diagram Ref No 21 And 22

What This Product Does:

• In the context of the engine / cooling / ventilation system, a “breather line” or “vent hose / vent line” allows controlled venting of crankcase or cooling system gases, or supports the cooling/overflow/expansion system to relieve pressure, direct vapour, or provide required venting.
• These hoses ensure air or vapour that builds up is not trapped in the engine/cooling system, allow system pressure to stabilise, and maintain correct service behaviour of the engine’s ventilation or cooling circuits.
• They also help prevent buildup of pressure/vapour that could otherwise lead to malfunction, leaks or driveability issues.

Symptoms Of Wear, Damage Or When To Replace:

• Hose visible damage, cracking, brittleness or detachment — Over time, heat and age degrade rubber/hose materials.
  
• Engine or cooling system venting issues — for example, if you smell vapour/odour, see coolant or oil vapour escaping in unusual places, or lid caps popping off unexpectedly.
  
• Unusual noise or hissing from the engine bay or venting hose areas—possibly indicating a leak or damaged hose.
  
• Performance degradation in the ventilation/cooling system—such as elevated temperatures, pressure spikes in cooling, or increased oil consumption if the hose is a crankcase breather.
  
• Poor condition hoses in older vehicles—since these parts are often overlooked in maintenance, especially with older 996 models, they may be degraded and benefit from preventive replacement.
  
  

Why Replacement Matters:

• Maintains correct system function: A properly functioning breather line ensures your engine’s ventilation/cooling systems are working as intended — preventing pressure buildup, vapour trapping or system inefficiencies.
• Prevents secondary damage: A failing hose might lead to undue pressure or vapour escaping in unwanted places, which can damage hoses, connectors, engine seals or other vulnerable parts.
• Helps reliability and longevity: Especially in older 996 models, replacing old, brittle, cracked hoses with fresh OEM-spec units avoids failures that can strand the vehicle or lead to more expensive repair.
• Peace of mind & maintenance value: Ensuring the ventilation path is intact supports the overall health of the engine and cooling system, which can matter for resale or restoration quality.

Water Hose.
Renew the coolant overflow connection on your Porsche Boxster with this genuine OEM overflow hose. Designed for the Boxster 1997-2008, this main fill/overflow hose links the cooling system to the expansion reservoir, ensuring proper coolant expansion, return flow and system pressure stability.

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02

• Porsche Boxster 987 2.7L 2005 -08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08

Diagram Ref No 29

What This Product Does:

• This hose functions as the connection between the cooling system (likely radiator or coolant header) and the overflow/expansion reservoir. When coolant expands under heat or pressure, surplus fluid flows into the reservoir; conversely when the system cools, fluid returns.
• Ensures that cooling system overflow is safely directed, that the reservoir receives the fluid, and that the cooling circuit maintains correct pressure, volume and recirculation.
• Proper operation helps avoid coolant loss, maintain correct cooling system levels, and helps prevent boil-over or overheating due to un-controlled coolant expansion.

Symptoms Of Wear Or When To Replace:

• Coolant leakage around the reservoir, hose clamps, or along the path of the overflow hose — e.g., dripping coolant, crusty residue near joints.
  
• Overheating or low coolant, where the expansion reservoir remains dry, suggesting the hose isn’t delivering returning fluid or has collapsed.
  
• Burst, cracked or hardened hose— rubber hoses degrade with heat/age, causing soft spots, bulges, cracks or collapse under pressure.
  
• Hose slack or loose clamps— if the hose is long out of service it might sag, the ends may be brittle, or clamps may be corroded leading to poor seal.
  
• If the vehicle is running very hot or the coolant level drops unexpectedly, and checks show the overflow system not functioning properly.
• On older Boxsters many cooling-system hoses are aged and replacement is preventive maintenance.

Why Replacement Matters:

• Maintains cooling system integrity: A faulty overflow hose can lead to coolant loss, pressure escape or improper reservoir return—affecting system performance and engine cooling.
• Prevents overheating or coolant loss: Since the hose handles expansion flows, failure can result in overflow at wrong points or low reservoir levels, which may lead to engine overheating or damage.
• Reliability and longevity: Rubber coolant hoses degrade over time due to heat, vibration and pressure cycles — replacing them restores system reliability.

Diagram Ref No 2

What This Product Does:

• This lock cylinder assembly sits behind the external door handle and is the mechanism which allows the door to be locked or unlocked via key from the outside.
• The keyed lock cylinder ensures security (locks the door), and the “coded” aspect ensures compatibility with the vehicle key system (which can include central locking or key-matched sets).
• Correct fitment ensures the door handle and lock engage properly, the key insertion is correct, the internal mechanism aligns and the lock both secures the door and allows smooth access.

Symptoms Of Wear Or When You Should Replace It:

• Key won’t turn, sticks or is difficult to insert—in the door handle lock area. This suggests the cylinder may be worn, corroded or jammed.
  
• Door won’t lock or unlock via the key from outside, or the key simply spins freely indicating internal cam/shear failure.
  
• Mismatched key numbers: if the door lock is not operating with your existing key, or you have two different keys for left/right doors and want to unify them.
  
• Corrosion or damage: the lock barrel may show signs of rust, binding, broken mounting tabs or wear of the key slot—common after many years of service.
  
• After bodywork or door replacement: If the door or handle assembly has been replaced or re-painted, the lock cylinder might be damaged or mismatched—installing a correct coded cylinder ensures proper fit.
  
• When restoring the vehicle or upgrading security: a key-matched cylinder ensures your doors work with the master key and reduces the number of keys.

Why Replacement Matters:

• Security: A worn or malfunctioning lock cylinder compromises door security—important for a performance car like the 993.
  
• Convenience: Ensures your existing key operates both sides (or the correct side) without needing multiple keys, re-keying or workaround.
  
• Fit & finish: OEM cylinders ensure correct handle fitment, proper alignment, correct key engagement, and preserve vehicle authenticity.
  
• Reliability: Avoids the situation where a worn cylinder fails entirely — meaning you cannot lock/unlock the door with the key from outside, which could be inconvenient especially if central locking is involved.
  
• Resale & value: For a classic like the 993, correct functioning door locks with key-matched cylinders contribute to overall restoration quality and value.

Diagram Ref No 9

What This Product Does:

• When you pull the release handle inside the car (or via the remote release), this cable is under tension and the movement pulls the latch lever on the rear lid, allowing the lid to open.
• The “guide tube” part provides support for the cable, keeps it aligned, prevents kinks or chafing, and helps maintain smooth operation.
• Without this cable functioning properly, the rear lid may not open (or may open unpredictably), causing inconvenience or failure to gain access to the engine bay/trunk area.

Symptoms Of Wear Or Failure:

• The lid release inside the cabin doesn’t operate the rear lid — i.e., you pull the handle and the lid doesn’t release.
  
• Sticky, stiff or jerky release operation — the cable may be sticking in the guide tube, stretched or frayed.
  
• Visible damage to the cable or guide tube — corrosion, frayed wire, broken sheath, kinks in the tube.
  
• Rear lid latch mis-behaviour — the lid may pop open unexpectedly, not latch properly, or you may need to repeatedly pull the handle.
  
• When restoring a vehicle or replacing rear lid components (hinges, latch, seal) the cable is often overlooked but can be worn due to age (especially in 964/993 cars).

Why Replacement Matters:

• Ensuring reliable access: The rear lid is your access point for the engine bay/trunk; a non-resilient or broken cable means you might be unable to open the lid when needed.
• Safety & utility: If the lid cannot latch properly or stays partially unlocked, this could cause it to fly open while driving or not secure properly.
• Prevents further damage: A worn cable can cause excessive load on the latch, hinge or release handle mechanism, accelerating wear or causing mis-alignment.

Diagram Ref No 15 And 16

What This Product Does:

The tail-pipe tip is the visible end section of the exhaust system. While it doesn’t typically affect engine performance directly, its functions include:

• Providing the correct physical outlet for the exhaust gases (ensuring correct alignment under the bumper, correct fitment).
• Contributing to the aesthetic/visual finish of the vehicle (chrome or polished tip, aligning with diffuser or bumper design).
• Protecting the exhaust outlet and ensuring a clean exit of gases (also potentially shielding nearby bodywork or trim).
• Correct tip fitment ensures the exhaust meets factory design for appearance and clearance, avoiding visible misalignment or poor fit.

Symptoms Of Wear Or Need For Replacement:

• The tip is visibly damaged, cracked, dented, corroded or the finish is peeling. Because the vehicle is used, external tips can suffer from road debris, salt, heat etc.
  
• The tip is loose or mis-mounted, or it doesn’t align properly with the bumper or diffuser — this could be due to broken brackets, missing hangers, or the tip section was replaced incorrectly.
  
• Exhaust gases are contacting bodywork or diffuser — if the tip is mis-aligned, hot gases or soot may mark adjacent parts.
  
  

Why Replacement Matters:

• Aesthetic & fitment: Because this part is highly visible on the rear of the vehicle, correct OEM fitment contributes to the vehicle’s finished appearance and preserves value.
  
• Structural integrity: A poorly fitting or damaged tip may cause vibration, hangers may sag, and the exhaust may shift — leading to other issues further up the system.
  
• Durability & corrosion protection: Original parts are designed for the specific application; replacing a worn tip prevents further degradation or build-up of rust/corrosion at the exit point of the exhaust.

Air Con Evaporator.
Restore the rear cabin air-conditioning performance on your Porsche 928 with this genuine evaporator unit (Part # 928 570 211 00). Designed for vehicles with the “Improved Efficiency” A/C option (M570) from around 1985 onwards, this direct-fit part replaces the original rear evaporator core and ensures proper cooling, airflow and de-humidification for the rear passenger compartment.

NOTE: LAST 1 IN STOCK

Fits:

• Porsche 928S2 4.7L 1984-86
• Porsche 928S4 5.0L 1987-92
• Porsche 928GT 5.0L 1989-91
• Porsche 928GTS 5.4L 1992-95

Diagram Ref No 19

What This Product Does:

• The evaporator is the component in the A/C system where the refrigerant enters the unit as a low-pressure liquid and absorbs heat from the cabin air, thereby cooling and de-humidifying the air that blows out to the cabin.
• In the rear A/C system of the 928, the evaporator is mounted within the rear HVAC housing and cools the air blowing into the rear passenger compartment.
• A properly functioning evaporator ensures the rear A/C system will deliver cold air, maintain correct charges of refrigerant, and operate efficiently.
• Since the 928’s air conditioning is sometimes used for extended periods (especially in warmer climates), the evaporator must be free of corrosion/leaks, have clean fins, and maintain proper airflow.

Symptoms Of Wear, Failure Or Need For Replacement:

• The rear A/C is not blowing cold, or takes much longer than usual to cool.
  
• Ice or frost formation on the evaporator core or housing — indicating restricted airflow or super-cooling.
  
• Leaking refrigerant: a crack or corrosion in the evaporator can cause refrigerant loss, evidenced by reduced cooling, a hissing noise, or oily residue in the HVAC box.
  
• Poor airflow or musty smell: a clogged, corroded or leaking evaporator may reduce airflow to the rear seats or cause musty odours from mold/moisture accumulation.
  
• Uneven temperature between front and rear zones (if applicable) — the rear section may lag or not reach set temperature.
  
• On inspection: visible corrosion, damaged fins, or signs of leaks around the evaporator housing, especially with older vehicles.

Why Replacement Matters:

• A failing evaporator not only reduces comfort (especially for rear passengers), but can lead to higher operating costs, increased wear on the compressor (due to low refrigerant charge or restricted flow), and potential damage to other components (such as blower motors, seals).
  
• For the 928, which is now a classic car, maintaining a fully functional A/C system helps preserve vehicle value and usability — especially if the car is driven in warmer climates or used for touring.
  
• Replacing the evaporator ensures the system remains efficient, prevents recurring refrigerant leaks, avoids breakdowns, and ensures correct integration with the rest of the HVAC system (expansion valves, driers, hoses).

Tiptronic Control Unit.
Restore proper centre differential/transfer-case lock control in your Porsche Cayenne 955 chassis, 2003-2004. This ECU module governs the longitudinal lock mechanism of the drive system, ensuring correct power distribution front to rear, correct 4WD behaviour and stable traction. Ideal for replacing a failed or malfunctioning unit, it enables your 4WD system to perform reliably.

Fits:

• Porsche 955 Cayenne 3.2L V6 2003-04
• Porsche 955 Cayenne S 4.5L V8 2003-04
• Porsche 955 Cayenne Turbo 4.5L 2003-04

Cars With Option Codes:
G0R - Tiptronic S

Diagram Ref No 8

What This Product Does:

• In 4WD/all-wheel-drive systems the “drive longitudinal lock” refers to locking mechanisms of the centre differential or transfer case — this ensures power is correctly distributed between front and rear axles.
• This ECU monitors and controls that locking system: it takes inputs (wheel speeds, differential states, driver commands) and commands the actuator (solenoids, clutches) in the transfer case or centre diff to engage or release the lock.
• Proper function ensures that the vehicle’s 4WD system behaves correctly (engaging or disengaging locks when required), which impacts traction, stability, driveability and sometimes road regulations (e.g., snow/ice mode).
• If this unit fails, the locking system can get stuck open or closed, produce fault codes, and affect driving behaviour (especially in low-traction or off-road situations).

Symptoms Of Failure Or Need For Replacement:

• A fault code related to the centre differential, transfer case, or “longitudinal lock” is present in the diagnostics.
• Loss of 4WD function or “lock” function — e.g., the vehicle stays in 2WD when it should lock, or it stays locked when it shouldn’t.
• Illumination of warning lamps related to drivetrain/4WD/traction.
• Unusual noises from the transfer case / centre diff (clutch slipping, grinding) that might be triggered by improper lock control.
• Intermittent behaviour (sometimes works, sometimes doesn’t) which can indicate ECU logic/actuator control failure rather than a purely mechanical fault.

Why Replacement Matters:

• Because the control unit is central to drivetrain behaviour, a fault here can drastically degrade vehicle performance, safety (traction/stability) and drivability.
• For a Porsche Cayenne early model (955), these units are becoming harder to source or may be superseded — replacing a failing unit proactively protects the vehicle.
• Restoring the correct function of the 4WD/centre differential lock restores the vehicle’s intended performance envelope, especially under load, off-road or in low-traction conditions.
• From a maintenance/resale perspective: a vehicle with a properly functioning transfer-case lock system is more desirable; faults here reduce value.
• Lastly, diagnosing and replacing the ECU early may prevent secondary damage (mechanical wear from improperly controlled locks/clutches).

What This Product Does:

• The universal steering joint (u-joint) allows the steering shaft to transmit rotational torque from the steering wheel through one or more bends or offsets in the shaft assembly. This is necessary because the steering column is not always in a straight line to the rack/box — the joint compensates for misalignment, angles, and movement.
• It also absorbs slight movement or misalignment in the column/shaft as the car body or chassis shifts under load, ensuring consistent steering input.
• A properly functioning joint ensures steering inputs are crisp and without slop, meaning the driver feels direct connection between the wheel and the road.
  
  

Symptoms Of Wear Or When To Replace:

• Steering play or looseness — the steering wheel feels vague or there is free movement before the wheels respond.
  
• Clicking, clunking, or knocking noises in the steering column area when turning the wheel, especially when stationary or slow speed.
  
• Vibration or harshness being felt through the steering wheel that wasn’t there before — could indicate joint wear.
  
• Difficulty maintaining alignment of the steering shaft or column, or if the joint appears visually worn or has excessive movement when the wheel is moved by hand.
  
• On inspection: the joint may show worn bearing surfaces, excessive play, corrosion or missing grease, or the coupling bolts may be loose or damaged.

Why Replacement Matters:

• A worn or failing steering joint compromises the connection between driver and car — which is a crucial safety and performance component.
  
• Replacing the joint restores steering precision, improves feedback and driver confidence.
• It prevents further damage: a sloppy joint can transfer misalignment or stress to other steering components (column, rack, couplings).
• If you’re restoring or upgrading a 964 / 993, fitting a new universal joint ensures the steering system is fresh and retains value.
• From a safety standpoint, the steering column is a critical interface — ensuring all joints are correct supports overall integrity.

Diagram Ref No 5

What This Product Does:

• The switch assembly allows the driver to manually request a gear up or gear down change via the steering wheel (or a stalk) in a car equipped with the Tiptronic or manual-mode automatic transmission.
• When pressed, the switch sends a signal to the transmission control unit (TCU) or shift logic unit, telling the system that the driver wants a gear shift (up or down). The system then executes the shift accordingly (assuming conditions are safe).
• It enables a more engaging driving experience: rather than fully automatic shifts, the driver can intervene via the steering wheel — especially useful for sporty driving or when you want more control.
• Since this switch is mounted in the steering column or wheel housing, it must integrate electrically and mechanically with the steering wheel, clock spring (slip ring), airbag wiring (if present), and shift logic.

Symptoms Of Wear Or Failure:

• Gear shift requests not registering: you press the paddle or switch and the transmission does nothing or delays shifting — the switch may not be signalling properly.
  
• Unexpected behavior: the shift logic may behave erratically (e.g., unintended shifts, no response) because the input is corrupted or erratic.
  
• Warning lights or error codes: your TCU or instrument cluster may log faults relating to gear shift input, steering wheel controls, or slip-ring/clock-spring issues.
  
• Physical damage or wear: the switch may feel loose in the wheel, or the button might require unusual force; wiring or connectors may be degraded; slip-ring may be worn causing intermittent signal loss.
  
  

Why Replacement Matters:

• Having a fully functioning shift-switch on a Tiptronic or manual-mode automatic is key for driver control and engagement. If the switch fails, you lose an important ergonomic interface.
  
• From a safety standpoint: faults in steering-wheel mounted switch modules can impact other systems (airbag wiring, steering-column controls) or cause unexpected behaviors — replacing a faulty assembly restores correct integration.
• For vehicles being restored, modified or where the steering wheel has been replaced/modified, ensuring the correct switch unit is fitted (and the “without cover” variant matches your wheel) is important for fitment, function and resale value.
• Proper repair avoids repeated diagnostic and repair costs. A degraded switch can lead to transmission control faults, which may require expensive fault-finding.
• Ensures longevity: wiring, mechanical integrity, and switch responsiveness degrade over time; replacing it pre-emptively improves reliability.
