Mercedes-Benz GLA Clutch Slave Cylinder Replacement Parts

Only GLA variants fitted with a manual gearbox have a clutch slave cylinder — and in practice, the vast majority of GLAs sold in the UK came with an automatic or dual-clutch transmission, meaning most examples never had this part at all. If your GLA has a manual gearbox, it will have a clutch slave cylinder, but you should confirm your exact gearbox type with your V5 or a VIN check before searching. If your GLA is automatic, there is no clutch slave cylinder — you may instead be looking for a transmission solenoid, valve body, or mechatronic unit depending on the fault.

The quickest check is your V5 registration document or a VIN decoder, which will show your gearbox type and engine code — the engine code is the single most useful detail for sourcing this part correctly. Manual-gearbox GLAs were offered on certain lower-displacement petrol and diesel variants, particularly in the first-generation X156 (2013–2019), but they were a minority of UK sales. When contacting a breaker, give them your engine code, gearbox code, and registration so they can match the correct unit from their donor vehicle.

The first-generation GLA runs as the X156 from 2013 to 2019, with a facelift arriving in 2017 — both pre- and post-facelift cars share the same platform, but whether ancillary components like the clutch slave cylinder changed at the facelift point is something you should confirm with the breaker against your specific registration and engine code. The engine code is the most reliable guide here, as mechanical parts follow the engine rather than the model year. A breaker can cross-reference the part number from the donor vehicle against yours to confirm compatibility before you commit.

Trim level — whether SE, Sport, AMG Line, or Executive — does not affect clutch slave cylinder fitment; this is a mechanical part determined by your engine code and gearbox type, not your trim specification. Bear in mind that cosmetic differences between trim levels (badging, interior finish) are irrelevant when sourcing this part from a breaker. Focus on supplying your engine code and gearbox type, and the trim name can be ignored entirely for this purpose.

Yes — the badge (200d, 220d, 250 etc.) points broadly to engine family, but the engine code stamped on your V5 or readable via a VIN check is more precise and is what a breaker will use to match the correct part. A diesel variant like the 220d and a petrol like the 250 will have different engine codes and potentially different clutch hydraulics if both happen to be manual-gearbox cars. Always lead with your engine code when contacting a breaker, rather than just the badge name.

Yes — if your GLA is fitted with a 7G-DCT dual-clutch automatic (which is common across GLA variants sold in the UK), there is no conventional clutch slave cylinder; the clutch actuation is handled internally within the transmission and controlled electronically. Symptoms like clutch judder, jerky low-speed behaviour, or gearchange issues on a DCT GLA are more likely to point toward the mechatronic unit, clutch pack, or transmission fluid condition. A breaker or specialist familiar with Mercedes dual-clutch units will be better placed to advise on the correct replacement part for your specific symptoms.
