Second Hand BMW X7 Differential

The BMW X7 (G07) launched in 2019 and received a significant facelift in 2022, bringing a revised front end and updates under the bonnet. For differential purposes, the key detail is always your engine code rather than the model year alone, as mechanical specifications can shift mid-production. Always supply your registration or VIN to the breaker so they can match against your exact build.

The 2022 facelift marks a meaningful production boundary for the G07 X7, and while some running gear can carry across, you should not assume a pre-facelift differential will drop straight in. Confirm your engine code from your V5 or a VIN check and give it to the breaker, who can verify whether the unit from a pre-2022 car matches yours exactly. Never assume fitment across a facelift boundary without that check.

Almost certainly not directly, because the xDrive30d is a diesel and the xDrive40i is a petrol, meaning different engine codes, different torque outputs, and likely different differential specifications. Mechanical parts follow the engine code above the badge, so always match by engine code first. Give the breaker both your engine code and the sourced part's engine code to confirm compatibility.

Yes, gearbox type matters for differential fitment because ratios and output configurations can differ. The X7 was sold in the UK exclusively with automatic transmission, but variants differ by engine, so your engine code remains the most important detail to cross-reference. Supply your engine code and gearbox code to the breaker to be certain.

Trim level alone — such as M Sport versus xDrive standard specification — does not determine differential fitment; what matters is the engine code and drivetrain setup underneath. An M Sport is largely a cosmetic and suspension package on the X7 rather than a mechanical variant, so a differential from an equivalent-engine M Sport and a non-M Sport car of the same engine code should be the same unit. That said, always confirm with the breaker against your registration, as there can be ancillary or mounting differences that are not always publicised.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or via a VIN check — it tells the breaker far more than the year or badge alone. Alongside that, provide your model year, fuel type, and registration number so the breaker can cross-reference the exact specification. The more precise you are upfront, the less risk of ordering a unit that does not match your car.
