34 35 001 Replacing a brake pad sensor (front)

WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.

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 an already sanded brake pad wear sensor has to be replaced although the MINIMUM BRAKE PAD THICKNESS has not yet been reached, it is necessary to file down the new sliding contact with a file to the same length as the sanded sliding contact.

Necessary preliminary tasks:

Remove front left WHEEL

Open housing cover.

Disconnect plug connection (1).
