Second Hand Mercedes-Benz A-Class Clutch Master Cylinder

Only manual-gearbox variants of the A-Class have a clutch master cylinder — if your car has an automatic, CVT, or dual-clutch (DCT/7G-DCT) gearbox, there is no clutch master cylinder fitted and you will not find one to buy. The W168 (1997–2004), W169 (2004–2012), and W176 (2012–2018) generations were all offered with manual gearbox options, so those variants do have this part. The W177 (2018–present) A-Class moved predominantly to automatic transmissions in the UK market, so confirm with a breaker whether your specific registration had a manual gearbox before searching. If your car is automatic and you have a hydraulic or fluid-related fault, the part you may actually be looking for is the brake master cylinder or a transmission-related component.

Both a 2008 and a 2011 A-Class fall within the W169 generation (2004–2012), but engine code is the key factor for this part — a cylinder from the same engine code is a much safer match than one simply from the same generation. The W169 received a facelift around 2008, and ancillary component changes can occur across a facelift even within the same generation, so confirm compatibility against your exact engine code and registration with the breaker rather than assuming year-to-year fitment. Never assume fitment solely on generation without cross-checking the engine code.

Trim level and badge (A150, A170, A200 and so on) do not directly determine which clutch master cylinder you need — what matters is the engine code, which you can find on your V5C or via a VIN check. Two cars with different badges can share an engine code and therefore the same clutch master cylinder, while two cars with the same badge but different engine codes may not interchange. Focus on supplying your engine code to the breaker rather than the trim name for the most accurate match.

The W168 and W169 are distinct generations with different platforms and engine families, so a direct swap across this generational boundary is unlikely to be straightforward. You should treat these as incompatible unless a breaker can confirm otherwise by checking your specific engine code and registration against their stock. Always route cross-generation fitment questions to the breaker rather than assuming parts interchange.

The W176 generation ran from 2012 to 2018 with a facelift in 2015, so a 2013 car is pre-facelift and a 2015 car could be either side of that boundary depending on build date. Engine code is still the primary guide here, and ancillary mounting or specification changes can occur across a facelift point even when the engine code matches — confirm fitment against your registration with the breaker rather than relying on year alone. Supplying your engine code alongside your registration gives the breaker the best chance of finding you a confirmed match.

The most useful details are your engine code (found on your V5C logbook or a VIN decoder), your full registration number, and confirmation that your car has a manual gearbox — without these, a breaker can only make an educated guess. The engine code matters more than the model year or trim badge, because Mercedes sometimes used the same engine code across multiple years and body styles, and a matching engine code is the strongest indicator of compatibility. The breaker can then cross-reference their stock against your exact specification and advise whether the part is a confirmed fit.
