Second Hand Mercedes-Benz C-Class AC Compressor

This crosses the W204 generation boundary — the W204 ran from 2007 to 2014, with a facelift in 2011, so a 2010 and a 2014 are both W204 but either side of that facelift. Fitment is primarily driven by engine code rather than year alone, so two cars sharing the same engine code (for example both running the M271 2.0 petrol) are a much stronger starting point than matching year to year. That said, whether ancillary bracket positions or fittings changed around the 2011 facelift is something you should confirm with the breaker against your registration before buying.

The W203 (2000–2007) and the W204 (2007–2014) are separate generations with different engine families, so the compressors are not a straightforward swap even where displacement looks similar on paper. Engine code is the detail that matters most here — supply your exact engine code (shown on your V5 or via a VIN check) to the breaker so they can cross-reference accurately. Do not assume fitment based on generation alone, and confirm directly with the breaker against your registration.

Trim level — whether SE, Sport, AMG Line, or any other — does not affect AC compressor fitment; these are cosmetic and equipment packages rather than mechanical variations. What determines fitment is your engine code, fuel type (petrol or diesel), and gearbox type, not the badge on the bootlid. You may find visual differences in brackets or ancillary covers depending on the donor car, but the compressor unit itself follows the engine, not the trim — confirm the engine code match with the breaker and you can disregard trim entirely.

The single most useful piece of information is your engine code, which is printed on your V5 logbook or available from a VIN check — for the C-Class this identifies the exact engine variant far more precisely than the badge or cc figure alone. You should also provide your fuel type, gearbox type (manual or automatic), and model year, as these can affect which compressor was fitted in production. Registration number is a useful shorthand the breaker can look up, but supplying the engine code directly removes any ambiguity.

The W205 generation ran from 2014 onwards and introduced revised engine families compared with the W204 (2007–2014), so these are not generally interchangeable. Even where an engine code appears similar across the generation change, mounting points and ancillary connections may differ — this is exactly the kind of cross-generation boundary question you should put to the breaker with both registrations or engine codes to hand. Never assume fitment across a generation boundary without the breaker confirming against your specific registration.

Sharing the same badge is a reasonable starting point but not a guarantee, because the C220d name has been applied to different engine codes across different generations and even within a generation. Within the W205 for example, production and supplier changes can mean the compressor spec varied during the model run, and whether a specific unit from an earlier or later build date is a direct swap is something to confirm with the breaker against your registration. Give the breaker your exact engine code rather than just the model name, and they can check interchange accurately.
