No two clutch slave cylinders are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
No — the GLS has never been fitted with a clutch slave cylinder on any variant. Every version of the GLS (X166, 2016–2019, and X167, 2019–present) uses a nine-speed automatic gearbox as standard with no manual option ever offered in the UK, meaning there is no clutch pedal, clutch mechanism, or clutch slave cylinder on this vehicle at all.
It's worth double-checking the diagnosis, as the GLS uses an automatic transmission which has no clutch slave cylinder whatsoever. If you're experiencing a gear-engagement or transmission fluid leak issue, you may be looking for a torque converter, transmission oil cooler pipe, or a gearbox valve body — confirm the exact fault with your mechanic and then search for the correct automatic transmission component.
This is not applicable, as the GLS does not have a clutch slave cylinder regardless of which generation of GL or GLS you compare it to. If you own an older GL-Class (X164, 2006–2012) and are searching for transmission components, bear in mind that model also came exclusively with automatic gearboxes in the UK, so a clutch slave cylinder would not be found there either.
No — trim level makes no difference here because the part simply does not exist on the GLS in any form; AMG Line and full AMG (GLS 63) variants all use automatic gearboxes without a clutch assembly. If you're looking for drivetrain parts specific to an AMG variant, confirm the part and engine code with a breaker against your registration to ensure you get the right component.
It is not possible on a GLS 400d, as this is an automatic-only model with no clutch slave cylinder fitted. A leak in that area of the vehicle on an automatic model is more likely to be a transmission fluid line, a hydraulic braking component, or a power steering component — take the vehicle back to your garage for clarification and search for the correctly identified part once confirmed.
