BMW X5: Replacing A Brake Pad Sensor (Front)
IMPORTANT: The brake pad wear sensor must be replaced once it has been removed (brake pad wear sensor loses its retention capability in the brake pad).
If a brake lining sensor that has already been ground has to be replaced even though the minimum brake pad thickness has not yet been reached, you must observe the following: The new sliding contact must be filed down with a file to the same length as the ground sliding contact.
Necessary preliminary tasks:
- Remove wheel.
Disengage cable guides (2).
Open cover (1) on plug housing.
Disconnect plug connection.
Disengage cable from cable guide (3).

Cooling System
The cooling system of the N54 engine consists of a radiator circuit and an
isolated oil cooling circuit. The fact
that there is an isolated oil-cooling circuit ensures that heat is not
introduced via the engine oil into the engine's
coolant system.
