Used BMW M4 Clutch Slave Cylinder

Only manual-gearbox M4s have a clutch slave cylinder — the M4 has been offered with both a six-speed manual and a seven-speed M DCT dual-clutch automatic, and later an eight-speed M Steptronic automatic, none of which use a conventional clutch pedal or slave cylinder at all. If your M4 has a manual gearbox, it will have a concentric slave cylinder (CSC) integrated into the bellhousing, so you do need this part. If your car has an automatic or DCT, there is no clutch slave cylinder to replace, and the issue you're experiencing is likely elsewhere in the transmission or hydraulics — confirm with a specialist which gearbox code your car has before searching.

The F82 M4 ran from 2014 to 2020 and used the S55 twin-turbocharged inline-six, while the G82 M4 launched in 2020 with the S58 engine — these are different engine families with different bellhousing and transmission architectures, so the slave cylinder from one generation will not cross to the other. Stick to parts from the same generation and the same gearbox type (manual only, as above). Always confirm the engine code from your V5 or a VIN check and supply it to the breaker when requesting a quote.

Trim level does not affect clutch slave cylinder fitment — what matters is the engine code, gearbox type, and generation. The Competition badge on the F82 and G82 M4 brings suspension, software, and cosmetic differences, but the engine code and manual gearbox specification remain the same as the equivalent non-Competition manual car. Tell the breaker your engine code and confirm your gearbox is the manual unit rather than relying on the trim name alone.

Both a 2014 and a 2017 M4 fall within the F82 generation (2014–2020) and share the S55 engine, so they are broadly from the same family. However, ancillary and mounting changes can occur during a production run, so you should confirm with the breaker that the specific part from the donor car matches your registration before buying. Supply your engine code and full registration to the breaker so they can check against the actual donor vehicle.

The F80 M3 and F82 M4 are closely related — both use the S55 engine and share the same manual gearbox and transmission architecture across the same 2014–2020 generation, making the slave cylinder a commonly cross-referenced part between them. That said, confirm with the breaker against both registrations before purchasing, as there can be mid-run changes that are not always reflected in part numbers alone. Supplying both engine codes gives the breaker the best chance of confirming a match.

The most important detail is your engine code, which you can find on your V5 logbook or via a VIN check — for the F82 M4 this will be S55, and confirming this rules out any confusion with other M-badged models. You should also confirm that your car has the six-speed manual gearbox, since automatic and DCT variants do not use this part at all. Your full registration number lets the breaker cross-reference against their stock and flag any ancillary differences specific to your build date.
