What This Product Does

The compressor raises refrigerant pressure and moves it around the air conditioning circuit. This enables the system to remove heat from cabin air and supports moisture removal during demisting. OE Match develops replacement components around Porsche applications, using original references and specification checks to assess suitability.

Functions

• Compresses refrigerant vapour for the cooling cycle.
• Circulates refrigerant through the air conditioning circuit.
• Supports cabin cooling and air dehumidification.
  
  

Technical Details

• Supplied references: 8T0260805N and PAB820803.
• Refrigerant requirement: R134A; vehicle option code KK1.
• Internal diagram application: 95B.1 Macan 2014–18, R4 2,0 TFSI, PR:DM0.
• Application covers the specified 2.0L I4 petrol variants only.
  
  

Symptoms of Fault

• Vent airflow remains warm despite a cooling request.
• Cooling becomes intermittent or noticeably weaker.
• Rattling or knocking develops around the compressor.
• Oil traces appear near a leaking compressor seal.
• Diagnostic pressure checks indicate inadequate compression.
  
  

Why Replacement Matters

A compressor may require renewal following seizure, leakage, excessive mechanical noise or loss of pressure generation. Establish the cause before fitting a replacement: refrigerant loss, insufficient lubrication, contamination and restrictions elsewhere in the circuit can contribute to failure. Internal damage may also release debris that requires further attention during repair.

FAQs

• Will regassing resolve weak cooling?
  Not necessarily. Check for leaks and confirm compressor operation rather than assuming a refrigerant top-up will solve the fault.
• Should the drier and circuit be checked?
  Yes. Assess drier replacement and cleaning requirements, particularly after an internal compressor failure.
• What about compressor oil?
  Confirm the specified oil and required quantity during installation; do not assume the supplied oil charge suits every repair.
• Who should install it?
  Refrigerant-system repairs should be undertaken by an appropriately qualified technician.

Air Con compressor - for Refrigerant R134a system (option code: KK1)
OE Match replacement air conditioning compressor engineered to reflect the specifications of the original Porsche unit. It’s designed as a direct-fit cooling system component for front air conditioning circuits in Porsche Cayenne 9YA/9YB models. The compressor pressurizes and circulates refrigerant - a critical step in generating cold air for the cabin.

Fits:
For cars with Refrigerant R134a (option code: KK1)
Porsche 9YA.1 Cayenne S 2.9L V6 2018 - 2023  (PR: TV8)
Porsche 9YA.1 Cayenne 3.0L V6 2018 - 2023  (PR: T9I)
  * not for Hybrid models

The compressor pressurizes refrigerant gas and sends it through the A/C system’s condenser and evaporator, enabling heat exchange that results in cool air delivered into the vehicle cabin. By matching OEM specifications, this part aims to provide stable cooling performance and compatibility with your vehicle’s HVAC system.

As the central pump in the air conditioning system, this compressor draws in low-pressure refrigerant gas, compresses it to high pressure, and pushes it to the condenser. This process allows the refrigerant to cool efficiently and support comfortable interior temperatures during hot conditions. Its flexible design accommodates proper belt alignment, system routing, and connection points.

An aging or failing compressor can lead to weak airflow, insufficient cooling, excessive noise, or complete loss of air conditioning. Replacing it with an OE-match unit restores effective refrigerant circulation, enhances comfort levels, and ensures the HVAC system functions reliably - without compromising fitment or performance

When to replace:
•  Warm or inconsistent air from the A/C vents
•  Noisy operation from the compressor area
•  Compressor clutch doesn’t engage
•  Visible leaks at seals or refrigerant ports
•  During A/C system servicing, recharges, or overhauls.

The compressor pressurises and circulates refrigerant through the air-conditioning system, enabling effective heat exchange and consistent cabin cooling. It ensures rapid temperature reduction, stable climate control operation, and optimal comfort for all occupants, even under high ambient temperatures.

This component draws in low-pressure refrigerant gas, compresses it to high pressure, and sends it to the condenser where heat is dissipated. Working in coordination with the condenser, expansion valve, and evaporator, it forms the core of the Cayenne’s HVAC system, supporting efficient cooling, defrosting, and interior climate regulation.

A failing A/C compressor can lead to reduced cooling performance, excessive noise, or complete loss of air conditioning. Using a Genuine Porsche replacement ensures correct system pressures, long service life, and full compatibility with factory components. OE parts help preserve vehicle reliability, comfort, and long-term value.

When to replace:
•  Warm or inconsistent air from the A/C vents
•  Noisy operation from the compressor area
•  Compressor clutch doesn’t engage
•  Visible leaks at seals or refrigerant ports
•  During A/C system servicing, recharges, or overhauls.
