Cheap Mercedes-Benz G-Class AC Compressor

The W463 G-Class ran from 1989 right through to 2018, but the engine range changed significantly across those years, and the AC compressor follows the engine code rather than the body generation — so a compressor from an early 1990s M102 or M103 petrol engine will not simply drop onto a later OM606 diesel or M273 V8 without checking codes carefully. The W463 was facelifted and re-engined multiple times, meaning ancillary mounting points and refrigerant system specs can differ across production years. Always confirm the engine code from your V5 or a VIN check and supply it to the breaker before agreeing a sale.

The W464 G-Class launched in 2018 as a full new-generation model with an all-new engine lineup, so it sits on a clear platform boundary from the outgoing W463. A compressor from a W463 is very unlikely to be a direct fit on a W464, and we would not recommend assuming compatibility across that 2018 boundary. Confirm your engine code and registration with the breaker, who can check against their specific unit.

Trim level and badge do not determine AC compressor fitment — what matters is the engine code, because the compressor is matched to the engine and its ancillary drive system. A G350d runs a diesel engine (typically the OM642 in later W463 production), while a G500 uses a petrol V8 and an AMG G63 uses a different AMG-tuned V8, so these will have different compressors to each other — but that difference is down to the engine, not the trim designation itself. Supply your exact engine code to the breaker rather than just the badge name.

Both a 2012 and 2014 G-Class fall within the W463 generation (1989–2018), so they share the same broad platform, but you still need to match on engine code because different engines were available across those years. Mid-production ancillary and mounting changes can also occur within a generation, so whether a 2012 unit physically fits a 2014 is something to confirm with the breaker against your specific registration rather than assume.

The single most useful detail is your engine code, which you can find on your V5 logbook or via a VIN check — it tells the breaker exactly which version of the compressor your car uses, far more reliably than the year or trim name alone. Also provide the model year and your registration so the breaker can cross-reference against their stock. Note that ECU pairing or any coding requirements for the replacement unit are something to discuss directly with the breaker, as we cannot confirm this as fact for your specific vehicle.

For a mechanical component like the AC compressor, drive-side (NS/OS orientation) does not affect fitment — the compressor mounts to the engine and is the same regardless of whether the donor car was right- or left-hand drive. What matters is that the engine code matches yours and that the unit came from a compatible model year. Confirm both with the breaker before purchasing.
