Second Hand BMW i4 Gearbox Mount

The BMW i4 is a fully electric vehicle and does not have a traditional gearbox or transmission in the conventional sense — it uses a single-speed reduction drive unit, so there is no gearbox mount of the type found on petrol or diesel BMW models. If you are hearing about a gearbox mount in relation to an i4, it is likely a misidentification; what you may actually be looking for is a motor mount (also called a drive unit mount), which secures the electric motor and reduction unit to the subframe. We would suggest searching for 'electric motor mount' or 'drive unit mount' for the BMW i4, and confirming the exact part with a breaker against your registration number.

Yes, the year can matter because the BMW i4 (G26) launched in 2021 and mounts can vary depending on the specific drive unit fitted — rear-wheel-drive variants use the eDrive35 or eDrive40 motors, while the M50 xDrive uses dual motors front and rear, meaning the mounting arrangements differ. Providing your exact registration or VIN to the breaker is the most reliable way to ensure you get the correct mount for your specific drive unit and drivetrain layout. Do not assume that all i4 motor mounts are interchangeable across the range without confirming with the breaker.

This is unlikely to be a straightforward swap, as the M50 is an xDrive model with dual electric motors — one on the rear axle and one on the front — whereas the eDrive40 is rear-wheel drive with a single rear motor, so the mounting configurations are different. The drive units themselves are different units, and the mounts are designed to suit each specific installation. Always confirm compatibility with the breaker by providing your full VIN or registration, and specify whether you need the front or rear drive unit mount on the M50.

No, the trim level — whether your i4 is a standard spec or M Sport — does not affect the motor mount, as this is a mechanical fitment driven by the drive unit and drivetrain layout rather than by trim or cosmetic specification. An eDrive40 M Sport and a standard eDrive40 use the same drive unit, so the mount should be the same. What matters is the drive unit variant and whether the car is rear-wheel drive or xDrive, so focus on those details when speaking to a breaker.

The BMW i4 (G26) has been in production from 2021 onwards as a single generation, but mid-production revisions can sometimes affect ancillary and mounting components in ways that are not always publicly documented. While early and later cars within the same generation often share mounts, whether a 2021-22 mount crosses into a 2023-24 car without issue is something you should confirm with the breaker against your specific registration rather than assume. Provide your VIN or registration plate and let the breaker verify compatibility directly.
