BMW 4 Series Gearbox Mount Replacement Parts

Yes, all BMW 4 Series variants have a gearbox mount — it is a rubber or hydraulic bush that locates the gearbox to the subframe or body and is a standard fitment regardless of whether the car has a manual or automatic gearbox. The 4 Series has always been rear-wheel drive or xDrive four-wheel drive, so unlike a front-wheel-drive-only platform, a conventional longitudinal gearbox with a mount is always present. You will find this part on every engine and trim variant of the 4 Series.

The F32 coupe, F33 convertible, and F36 Gran Coupe are all first-generation 4 Series (2013–2020, facelift 2017) and share the same platform, so the gearbox mount is generally common across those body styles for the same engine and gearbox combination. What matters most for fitment is the engine code and whether the car has a manual or automatic gearbox — body style itself does not affect which mount is fitted. Confirm the exact part against your registration with the breaker before ordering.

Trim level does not affect which gearbox mount is fitted — Sport, M Sport, xLine, and Luxury are cosmetic and equipment packages rather than mechanical variants, so they share the same gearbox mounts for a given engine and gearbox combination. The engine code is what drives the correct part selection, not the badge on the boot. Do be aware that a used mount pulled from a different trim car may carry minor cosmetic differences in its bracket or heat shielding, so check that with your breaker.

The F3x generation 4 Series ran from 2013 to 2020 with a facelift arriving in 2017, and in many cases the gearbox mount carries over across that boundary because the core drivetrain architecture did not change. However, mounting and ancillary components can change mid-production without an obvious external facelift, so you should not assume interchangeability across the 2017 boundary without checking. Give your registration and engine code to the breaker and ask them to confirm the part number matches before you commit.

Engine code is the single most important factor here — different engines (for example, a B47 diesel versus a B58 petrol) can have different gearbox and mounting configurations, so a mount from one engine family may not suit another. Fuel type alone is not sufficient; the full engine code found on your V5 or via a VIN check is the detail that the breaker needs to find the right part. Supplying that code when you request a quote will save time and reduce the risk of ordering the wrong mount.

The G22 is the second-generation 4 Series, launched in 2020, and it uses a different platform and updated drivetrains compared with the F32/F33/F36 generation (2013–2020), so the gearbox mounts are unlikely to interchange between generations. The two generations are a clear fitment boundary, and crossing it for a mechanical mounting component is not advisable without direct confirmation. Give your registration and engine code to the breaker and ask them to verify the part is sourced from a G22 donor vehicle.
