Second Hand Mercedes-Benz GLE AC Compressor

The GLE (W166 generation, 2015–2019) shares its platform throughout that run, so a 2016 and a 2019 are within the same generation — but whether the compressor actually crosses over depends first on the engine code, which must match exactly, and then on gearbox type and fuel type. Name the generation boundary confidently: the W166 ends at 2019 and the all-new V167 starts from 2019 onwards, so a 2019 car could be either generation depending on exact registration date. Confirm the engine code from your V5 or a VIN check and ask the breaker to match against your registration before buying.

The 350d is a diesel and the 400 is a petrol, so these run entirely different engines with different compressor setups — fuel type is a hard fitment barrier here and the parts will not interchange. Engine code is the deciding factor above everything else, so check your V5 for the exact code and supply it to the breaker. Do not assume two GLE badges are compatible just because the body looks identical.

Trim level — whether that is Sport, AMG Line, or any other GLE trim — does not affect AC compressor fitment; this is a mechanical part that follows the engine code, not the badge or specification pack. You may find the compressor itself looks identical across trim levels on the same engine, though ancillary brackets or mounting details can occasionally vary mid-production, so ask the breaker to verify against your registration. The engine code from your V5 is the one detail that matters most here.

The V167 GLE (Mercedes revised the internal code to V167 for this generation) launched in the UK from 2019 onwards, replacing the W166. Within the V167 generation, engine code and fuel type still determine whether an AC compressor will interchange between an earlier and a later car in that run. Confirm with the breaker against your registration, as ancillary and mounting changes can occur mid-production without a formal facelift announcement.

Body style does not affect AC compressor fitment — what matters is the engine code, fuel type, and gearbox type, all of which can be identical across the GLE and GLE Coupé variants if they share the same drivetrain. If the engine codes match, the compressor is very likely to be the same unit, but confirm with the breaker against both registrations before purchasing. Never assume fitment purely on the basis that two cars carry the same GLE name.

Whether a used GLE AC compressor requires ECU pairing, immobiliser coding, or any electronic initialisation after fitting is something you must confirm directly with the breaker or a Mercedes specialist against your specific registration — this is not something we can state as fact here. Some Mercedes systems do involve electronic communication between components, and a used unit from a different car may need attention before it operates correctly. Ask the breaker this question explicitly before you agree a price, so you can factor in any additional workshop time.
