How to identify BMW AL differential
BMW AL differentials are commonly found in many F-Series models. The most reliable way to confirm whether your car uses a 205AL or 225AL differential is by checking your VIN in the BMW parts catalog or by physically inspecting the differential housing.
- 205AL is typically used in lower torque petrol and diesel models.
- 225AL is usually found in higher torque applications such as 530d, 535d, 550i, 640d, 650i and similar versions.
- VIN check is always recommended because fitment can vary depending on engine, drivetrain and market.
- If you are unsure, send us your VIN number or a clear photo of the differential and we will help you identify the correct repair kit.
Tip: BMW can use different rear differential versions within the same chassis depending on engine and xDrive configuration, so model alone is not always enough.
