Second Hand Mercedes-Benz GLC Clutch Slave Cylinder

No — the GLC has never been fitted with a clutch slave cylinder on any variant sold in the UK. Every GLC uses an automatic gearbox (either a 9G-Tronic torque-converter automatic or, on some AMG and 4MATIC+ versions, a wet multi-clutch unit), and none have ever been offered with a manual gearbox. Because there is no manual clutch system on any GLC, a clutch slave cylinder is not a part that exists on this vehicle.

Almost certainly yes — it is likely a mix-up, either with the wrong part name or the wrong vehicle. You may want to double-check whether the part you actually need is something like a transmission actuator, a clutch actuator (for the wet dual-clutch unit on some AMG variants), or a brake component, all of which do exist on the GLC. Share your exact registration and engine code with the breaker so they can identify the correct part for your specific gearbox type.

This question doesn't apply to the GLC, because the GLC does not use a manual gearbox and therefore has no clutch slave cylinder to replace. While the GLC shares its platform with the C-Class (W205/W206), the C-Class was offered with a manual gearbox in some markets — but that does not mean the clutch parts carry across to the GLC, which never had one. If you're sourcing a different part that is shared between the C-Class and GLC platforms, confirm compatibility against your registration and engine code with the breaker.

In this case, the engine code doesn't change the answer — no GLC variant, whether diesel or petrol, AMG Line or otherwise, was ever built with a manual gearbox, so none of them have a clutch slave cylinder. If you are searching for a gearbox-related part on your GLC, the engine code and gearbox type are still the most important details to give a breaker, as they will determine which transmission components apply to your car. Confirm exactly which part you need with the breaker using your registration number.
