BMW X4 Seat Belt Replacement Parts

The BMW X4 has been made in two generations: the F26 (2014–2018) and the G02 (2018–onwards, with a facelift in 2021). Seat belts are generation-specific, so an F26 belt will not cross-fit into a G02 and vice versa. When getting a quote from a breaker, confirm which generation your car is by giving them your registration.

This question sits right on the generation boundary: the F26 ran from 2014 to 2018 and the G02 started from 2018, so a 2016 car is F26 but a 2018 car could be either generation depending on exact build date. You should confirm your generation with the breaker against your registration before ordering, as belts from these two generations are unlikely to interchange.

For the BMW X4, the trim level (xLine, M Sport, M40i and so on) can influence seat belt style — for example, M Sport models may have different coloured stitching or belt surrounds — but the fundamental fitment is determined by generation and the side you need (nearside/NS or offside/OS). A belt from a different trim within the same generation will physically fit, but you may notice a cosmetic difference such as stitching colour not matching your interior. Tell the breaker your trim so they can try to match the finish.

Yes — nearside (NS, left/passenger) and offside (OS, right/driver) seat belts are handed and are not interchangeable. Always specify to the breaker which side you need, and for rear belts also clarify whether it is a centre, NS, or OS rear position. Getting this wrong is the most common fitment mistake with seat belts.

BMW X4 seat belts with pretensioners are safety-critical components, and professional fitting by a qualified technician is strongly recommended. Pretensioner belts are single-use — once fired in an accident they must be replaced and cannot be reset — and incorrect installation could mean the system fails to protect you in a collision. Ask the breaker to confirm the pretensioner variant matches your car's SRS system against your registration, as this is not something to assume.

The G02 BMW X4 received a facelift in 2021, and while both sit within the same generation, there may be differences in pretensioner variants or anchorage points between pre- and post-facelift cars. We cannot confirm as fact whether these interchange — route this question directly to the breaker and have them check against your registration plate to be sure before purchasing.
