xBentley Bentayga A/C Compressor 4M0820803N
Part number 4M0820803N — written by Bentley as 4M0 820 803 N — is a refrigerant compressor built for the climate-control system on compatible Bentayga models.
Within the A/C circuit, this is the component that keeps refrigerant moving and under pressure, which is what lets the system pull heat out of the cabin and deliver cooled air through the climate-control system.
Catalogue documentation ties 4M0820803N firmly to Bentayga variants running the 6.0L W12 petrol engine or the 4.0L V8 diesel, both on R134a refrigerant.
Mechanically, the compressor takes in low-pressure refrigerant and pushes it out at higher pressure toward the rest of the refrigeration circuit — so if this part isn't working correctly, the whole cooling process suffers.
Signs of a failing compressor include weak or absent cabin cooling, odd noises from the compressor, erratic A/C behavior, or contamination showing up in the refrigerant circuit. That said, none of these symptoms points exclusively to the compressor.
A low refrigerant charge, a leak somewhere in the circuit, a faulty pressure sensor, wiring problems, a failing condenser, expansion-control issues, or other HVAC faults can all produce much the same complaints. That's why the full A/C system needs a proper professional diagnosis before anyone commits to swapping the compressor.
In documented Bentayga applications, 4M0820803N is the current reference that supersedes the older 4M0820803H part number.
Refrigerant type is one of the fitment details that matters most here. 4M0820803N is documented specifically for W12 and V8 diesel Bentayga vehicles running R134a — it isn't a part to drop into a car built for a different refrigerant.
Any compressor replacement calls for the proper professional equipment and Bentley's workshop procedures when servicing the refrigerant circuit, along with a check of the system for whatever contamination or fault may have caused the original failure.
European Auto Spares supplies Bentley A/C compressors, condensers and other HVAC components, backed by worldwide delivery and professional VIN verification.

Not sure which Bentley A/C compressor you need?
Fitment for the Bentayga's A/C compressor shifts with engine, production date and refrigerant type. Refrigerant matters most: 4M0820803N is documented for R134a-equipped W12 petrol and V8 diesel Bentaygas specifically.
Send European Auto Spares your complete VIN so the right compressor can be confirmed before you order.
Getting Bentley cabin cooling back on track
The refrigerant compressor ranks among the most critical parts of the climate-control system — when it's struggling, A/C performance and cabin comfort both take a hit.
Get the system properly diagnosed first, so you know what's actually causing the cooling problem before any part gets replaced. If the compressor turns out to be the fault and 4M0820803N is confirmed compatible, that's the part to fit.
Passformdetails
xFitment Details – Bentley Bentayga A/C Compressor 4M0820803N
| Model | Application |
|---|---|
| Bentley Bentayga – 6.0L W12 Petrol – R134a | A/C Refrigerant Compressor |
| Bentley Bentayga – 4.0L V8 Diesel – R134a | A/C Refrigerant Compressor |
Important: 4M0820803N should not be treated as universal across every Bentayga. The strongest documented fitment is W12 petrol and V8 diesel vehicles using R134a. V8 petrol or vehicles with a different refrigerant/HVAC configuration require VIN verification. 4M0820803H is the previous reference superseded by 4M0820803N.

xFrequently Asked Questions – Bentley Bentayga A/C Compressor 4M0820803N
It's an air-conditioning / refrigerant compressor fitted to compatible Bentley Bentayga models.
The clearest documented application is the Bentley Bentayga.
Yes. It is documented for compatible W12 petrol Bentaygas running R134a refrigerant.
Yes. It is also documented for compatible V8 diesel Bentaygas using R134a.
Do not assume it does. The strongest Bentley-specific documentation names W12 petrol and V8 diesel applications, so a V8 petrol Bentayga requires VIN verification before ordering.
It is documented for compatible Bentayga applications running R134a.
Yes. 4M0820803H is documented as the earlier reference superseded by 4M0820803N.
Possible symptoms include weak or absent cabin cooling, unusual compressor noise, erratic A/C operation, compressor seizure or mechanical failure, and contamination in the refrigerant circuit. Professional diagnosis is required because other A/C faults can produce similar symptoms.
Yes. European Auto Spares lists both Genuine Bentley and Aftermarket options under 4M0820803N. This product page is the Aftermarket listing.
Yes. Provide the complete 17-digit VIN so the engine, refrigerant system and compressor application can be verified before ordering.
