Used BMW M4 Parking Sensor

Parking sensors were available on the BMW M4 (both the F82 generation, 2014–2020, and the G82 generation, 2021–present) but were not always fitted as standard — they were frequently an optional extra or part of a technology package, so not every M4 will have them. Before buying a used sensor, check your own car has the sensor housings and wiring already present in the bumper, as a car not optioned with parking sensors from new will need more than just the sensors themselves. Confirm with the breaker that the part came from an M4 with the same generation and bumper setup as yours.

No — the F82 and G82 M4 are entirely different generations with different bumper designs, connector types, and PDC control systems, so sensors from one will not fit the other. Always make sure the sensor you're buying came from the same generation as your car. Confirm compatibility with the breaker against your registration before purchasing.

The F82 M4 received a light refresh during its production run (around 2017), but the bumper and sensor architecture remained largely consistent across the generation, making interchange likely in many cases. That said, whether sensors from an earlier car swap cleanly into a later one is something you should confirm with the breaker against your registration, as minor wiring or housing differences can catch buyers out. Don't assume fitment without checking.

Trim level does not fundamentally affect parking sensor fitment on the BMW M4 — the sensors themselves and their housings are determined by the bumper specification and whether parking sensors were optioned, not by whether the car is a standard M4 or a Competition model. You may find cosmetic differences such as sensor colour or finish if the donor car had a different paint code, but the underlying part should interchange. Confirm the sensor colour matches or can be painted, and verify with the breaker that the donor car was from the same generation as yours.

This is a commonly asked question, but the BMW M4's bumpers are wider and differently shaped than those of the standard 4 Series, so sensor housings and the number of sensors fitted can differ. The PDC sensors themselves (the cylindrical transducers) may share the same part number in some cases, but the housings and fitment positions may not align correctly. Route this question to the breaker and confirm against your registration, as getting this wrong means the sensors won't sit flush or may not read correctly.

BMW M4 models fitted with parking sensors typically have four sensors in the rear bumper, and cars with front parking sensors add a further four at the front — but the exact configuration depends on what was optioned on that specific car. If you're replacing a single faulty sensor, you ideally want one from a matching bumper position (the corner sensors and centre sensors can differ in angle), so tell the breaker which position you need. Confirm the sensor count and position with the breaker against your registration to make sure you receive the right unit.
