 Note:

Integral ABS After switching on the ignition, always 
wait for the BMW Integral ABS to complete its self-
diagnosis. Do not operate the brake lever until the 
self-diagnosis routine has been completed.

faults, settings) stored in the Motronic control unit’s 
memory.
Loss of settings can temporarily impair the operat-
ing characteristics when the engine is restarted.

Installation is the reverse of the removal proce-
dure (
