BMW M4 AC Compressor Replacement Parts

The F82 M4 generation ran from 2014 to 2020, so both years sit within the same generation and share the S55 twin-turbocharged inline-six engine code, making a compressor from either year a strong candidate for fitment. However, ancillary mounting or bracket changes can occur mid-production without a generation change, so confirm with the breaker against your specific registration before buying. Never rely on year alone — supply your engine code, which you can find on your V5 or via a VIN check.

Both the 2014 launch car and the 2020 model sit within the F82 M4 generation (2014–2020), and both use the S55 engine, so the compressor is likely compatible in principle. That said, 2020 sits right at the close of the generation and minor ancillary changes can occur late in a production run, so confirm with the breaker against both registrations before committing. Supplying your engine code alongside the registration is the most reliable way to get an accurate answer.

The F82 generation ran 2014–2020 and uses the S55 engine, while the G82 generation launched in 2021 with the S58 engine — these are different engine families, so the AC compressor is very unlikely to be a direct swap. The mounting arrangements, drive configuration and electrical connections differ between the two generations, making cross-generation fitment highly improbable. Stick to parts quoted from the same generation and engine code as your own car.

For the AC compressor, engine code is what matters for fitment — both the standard F82 M4 and the M4 Competition use the S55 engine, so the Competition badge itself does not affect which compressor fits. Trim level differences on the M4 are largely focused on suspension tuning, exhaust, and interior specification rather than the air conditioning system. Confirm the engine code matches and check with the breaker against your registration, but you do not need to limit your search to Competition-sourced parts specifically.

For the F82 M4 (2014–2020), the engine code you need to quote is S55 — this twin-turbocharged 3.0-litre inline-six is the defining detail for compressor fitment, far more useful than quoting a year or trim level alone. You can find your engine code on your V5 logbook or by running a VIN check through a number of free online services. Always give the breaker your registration and engine code together so they can cross-reference their stock accurately.

The F80 M3 (2014–2018) and the F82 M4 (2014–2020) both used the S55 engine, so there is a genuine possibility the AC compressor is shared across these two models. However, whether ancillary fitment, bracket positions or electrical connections are identical is something you should confirm with the breaker against both registrations, as platform siblings do not always share every component. Providing both engine codes and registrations gives the breaker the best chance of confirming compatibility before you purchase.
