Pierburg

Pierburg for Porsche

Pierburg has traditionally been one of the closest partners to the automotive industry and has supported the development of the car since its beginnings. Founded in 1909 in Berlin as a steel trading company, Pierburg began to produce carburettors in 1928 and soon became virtually the sole supplier to all German automotive companies and many international vehicle producers and engine manufacturers. In 1986, the company was taken over by the Rheinmetall group.Pierburg is now the specialist within the group for the fields of emission control, air supply and throttle valves. Its decades of Porsche experience and comprehensive, innovative and renowned expertise when it comes to engines provide ideal foundations for Pierburg in the ongoing development and production of pioneering components, modules and systems.

Choosing the Right Fit for Your Porsche

Where Pierburg is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

• Typical reasons to choose Pierburg parts include fixing drivability issues, restoring correct fuel or air delivery, and renewing ageing components that cause intermittent faults.
• Common symptoms that lead to replacement are hesitation, poor idle, lean or rich running faults, hard starting, loss of power under load, and issues worsened by vacuum leaks or weak electrical supply.
• Before replacing components, smoke-test intake and vacuum lines, and check fuel pressure and basic wiring/grounds, as vacuum leaks or low pressure can mimic a faulty pump or valve.
• In some cases, control units may require adaptation reset or basic settings after installing new parts, depending on the specific component and vehicle system.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Cooling — Cooling parts are replaced when there are leaks, overheating, repeated low coolant warnings, or ageing hoses and clamps. Real-world early warnings include a sweet coolant smell, visible puddles, steam, rising temperature gauge, bubbling or gurgling after shutdown, and staining or residue around radiators, hoses, or undertrays.

• Check coolant level regularly and inspect for staining or dampness around joints, expansion tanks, radiators, and pump/thermostat areas.
• Avoid driving with known leaks or overheating, as this can quickly lead to severe engine damage.

Water / Coolant Pumps — Water pumps are replaced when bearing wear, seal failure, or impeller damage leads to leaks, noise, or reduced coolant flow. Typical symptoms include coolant weep at the pump, dried residue around the housing, whining or grinding from the pump area, wobble at the pulley, repeated low coolant warnings, and overheating in traffic or under load.

• Inspect for staining or wetness around the pump and listen carefully for bearing noise with the engine running.
• Because labour overlaps, many owners replace the thermostat and related cooling parts at the same time as the pump, especially during major services.

Engine Rebuild Parts — Engine rebuild parts are used when internal wear or damage is identified, or during planned overhauls to restore performance and reliability. Real-world triggers include low or uneven compression, heavy oil consumption, smoke under load or on overrun, persistent oil leaks, abnormal knocking or tapping noises, metallic debris found in the oil, low hot-idle oil pressure, or misfires that do not resolve after ignition and fuelling checks.

• Before committing to a rebuild, typical checks include compression and leak-down testing, bore inspection with a scope, oil analysis and filter inspection, and confirming that ancillary systems are working correctly.
• When the engine is apart, many specialists renew timing chains, guides, tensioners, bearings where applicable, gaskets, seals, and key hardware to avoid repeat strip-downs.

Oil System Parts — Oil system components are replaced to restore correct oil pressure and flow, stop leaks, and protect the engine from lubrication-related damage. Common real-world signs include oil drips under the car, oil-smell after driving, wet engine or undertrays, fluctuating or low oil pressure readings at hot idle, warning lights, perished hoses, and oil mist around breathers or unions.

• Treat oil pressure warnings as urgent: stop, verify the oil level and condition, and confirm pressure with proper testing where possible.
• Many owners choose to renew multiple lines, seals, and related fittings together so they are not chasing several small leaks over time.

Oil Pumps & Gaskets — Oil pumps and their gaskets are changed when internal wear or sealing issues lead to low or unstable oil pressure, slow pressure build on start-up, or leaks around the pump area. Symptoms can include low hot-idle pressure, pressure that drops sharply with temperature, ticking valvetrain noise when hot, warning lights, or oil seepage from case joints where gaskets have aged.

• Confirm real oil pressure with proper testing, as faulty senders or switches can sometimes mimic pump problems.
• When the engine is opened for major work or a rebuild, pumps and all associated gaskets and seals are often renewed as a preventive measure to reduce future risk.
