Mercedes-Benz A-Class AC Compressor Replacement Parts

This crosses a significant generation boundary: the W168 ran from 1997 to 2004, while the W169 ran from 2004 to 2012, so a 2005 unit and a 2009 unit are both W169 and sit within the same generation. That said, fitment ultimately depends on matching engine codes rather than model year alone, so supply your engine code (found on your V5 or via a VIN check) to the breaker so they can confirm the compressor is a true match. Never assume fitment on year alone.

The W168 (1997–2004) and the W169 (2004–2012) are separate generations with different engines, so the compressor from a W168 is very unlikely to cross to a W169. Confirm this boundary with the breaker against your exact registration and engine code before ordering, as mounting points and refrigerant connections can differ between generations. Do not assume cross-generation interchangeability.

Yes, fuel type matters because petrol and diesel variants of the same generation often use different engines with different compressor drives and mounting arrangements, so a diesel unit should not be assumed to fit a petrol car and vice versa. The engine code is the most reliable guide here — check your V5 or run a VIN check to confirm the exact code, then give that to the breaker. Matching on engine code rather than fuel type label alone is the safest approach.

In most cases the AC compressor itself is driven off the engine rather than the gearbox, so manual versus automatic should not directly determine which compressor is used. However, ancillary bracket and mounting arrangements can sometimes differ between variants built for different transmissions, so it is worth telling the breaker your gearbox type alongside your engine code when requesting a quote. Your engine code remains the single most important detail to supply.

Trim level — whether SE, Sport, or AMG Line — does not affect which AC compressor is fitted, because the compressor follows the engine code, not the badge or trim specification. A compressor from an AMG Line car with the same engine code as your SE or Sport should be mechanically equivalent, though you may find minor cosmetic differences in bracketry finish or ancillary clips that do not affect function. Confirm the engine code match with the breaker before purchasing.

The W169 did receive a facelift in 2008, which means your 2010 car is a post-facelift model, and some ancillary and mounting details can change across a facelift even within the same generation. Whether the compressor specifically changed at that point is something you should confirm with the breaker against your exact registration and engine code, as this falls into the category of mid-production changes that are difficult to state as fact without checking the specific unit. Supply your engine code to the breaker for the most reliable answer.
