What This Product Does

The compressor pressurises refrigerant vapour and drives its circulation around the air conditioning circuit. This allows the system to transfer heat away from the cabin.

Functions

  • Compresses refrigerant vapour.
  • Feeds pressurised refrigerant towards the condenser.
  • Supports the refrigeration cycle used for cabin cooling.

Technical Details

  • Brand: Mahle.
  • Supplied product reference: 9P1820803B.
  • Compressor reference in the supplied diagram: 9P1820803D.

Symptoms of Fault

  • Vent air remains warm with cooling selected.
  • Rattling or knocking from the compressor area.
  • Oil staining around a leaking compressor seal.
  • Insufficient pressure difference during an air conditioning system test.

These symptoms do not confirm compressor failure alone. Refrigerant loss, condenser damage and electrical faults should also be investigated.


Why Replacement Matters

A compressor with internal wear, seizure or leakage may no longer provide the refrigerant flow needed for cooling. Diagnose the original fault before fitting a replacement, particularly where contamination or inadequate lubrication contributed to failure.


FAQs

  • Will regassing fix the problem?
    A recharge will not repair mechanical compressor damage or an unresolved refrigerant leak. Establish the cause of weak cooling first.
  • Should the oil charge be checked?
    Yes. Confirm the lubricant specification and quantity for the vehicle and replacement compressor; do not assume the supplied oil charge matches the complete system requirement. 
  • Does the system need cleaning after internal failure?
    Inspect for contamination and follow the compressor installation instructions. Some components require replacement rather than flushing, especially where metallic debris is present.

The air con compressor compresses and circulates refrigerant through the A/C system. It helps provide the pressure needed for the refrigerant to move through the condenser, expansion valve, evaporator, and related climate control components, allowing the system to produce cold air inside the cabin.

Functions
•  Replaces the air conditioning compressor
•  Compresses and circulates A/C refrigerant
•  Supports correct cabin cooling performance
•  Helps restore reliable climate control operation
•  Suitable for air conditioning system repair or overhaul
•  Replaces failed, noisy, leaking, seized, or weak compressors
 OE Match replacement for Porsche A/C system service.

Why Replace This Part?
Air con compressors can fail due to age, internal wear, refrigerant leaks, lack of lubrication, contamination, clutch or pulley issues, electrical faults, or long periods of non-use. A faulty compressor may cause poor cooling, no cold air, unusual noise, refrigerant pressure faults, A/C warning issues, or a seized compressor. Replacing the compressor helps restore correct refrigerant circulation and cooling performance.

When to Replace This Part
•   The air conditioning no longer blows cold air
•   The compressor is noisy, seized, weak, or leaking
•   Refrigerant pressure faults are present
•   The A/C system has suffered internal compressor failure
•   Climate control performance is poor or inconsistent
•   The compressor pulley or clutch area is faulty
•   The A/C system is being overhauled or repaired.

Where it fits on the car
This compressor fits within the engine-driven air conditioning system on Porsche 997, 991, Boxster, and Cayman models. Exact location and installation layout can vary depending on model and engine type.
