Used BMW i4 Bulkhead

The BMW i4 launched in 2021 on the G26 platform and remains in its first generation as of 2025, so bulkheads from 2021 onwards are broadly from the same generation. A facelift (LCI) arrived for the 2024 model year, and while the platform is shared, whether the bulkhead pressing changed at that point is something you should confirm with the breaker against your registration before buying.

The 2022 and 2024 i4 both sit on the G26 platform, but 2024 marks the LCI facelift, which can bring subtle bodyshell changes even where the underlying architecture is the same. Name the pre-2024 and post-2024 boundary to your breaker and ask them to cross-reference the part against your specific registration to confirm interchange before purchasing.

Trim level does not affect bulkhead fitment — the i4 eDrive35, eDrive40, and M50 all share the same four-door Gran Coupé bodyshell on the G26 platform, so the bulkhead is the same pressing regardless of which variant you have. You may find that donor cars from M50 models carry additional underbody reinforcement or bracing in the engine bay area, so flag this to the breaker if you want a like-for-like match on any attached brackets or mounts.

The i4 and the combustion-engined G26 4 Series Gran Coupé share the same platform and body style, which suggests a close relationship between their bodyshells. However, whether the bulkhead pressing is genuinely identical or differs due to EV-specific firewall requirements is something you should confirm with the breaker against your registration, as we cannot state this as fact.

For a UK right-hand-drive i4, you should always specify RHD to the breaker, as the bulkhead can differ between left- and right-hand-drive vehicles due to the placement of the steering column aperture and associated reinforcements. A LHD bulkhead sourced from a European market car will not be a straightforward fit on a UK-spec i4.

The BMW i4 is offered exclusively as a four-door Gran Coupé in the UK, so there is only one body style to consider and no cross-body-style fitment risk within the i4 range itself. If a breaker is offering a bulkhead described as coming from a different 4 Series body style, such as the two-door coupé or convertible, confirm with them that it originates from a G26 Gran Coupé before proceeding.
