How often will I need BMW M850i xDrive differential service?

Can you clear the M850i xDrive check engine light on your own?

While it’s sometimes possible to clear a malfunction warning light at home, it’s never recommended. If your M850i xDrive’s check engine light comes on, it’s usually because there is a problem in one of the vehicle’s systems.

By simply resetting the check engine light, you may temporarily get rid of the light, but the underlying problem is still there. It will only be a matter of time before the light comes back.

How worried should I be about a drivetrain malfunction in my M850i xDrive?
