BMW F650 FS (2001–2009)
What the hazard is
If engine oil enters the brake booster, it may damage the internal rubber membrane, causing it to develop leaks and possibly impair the brake power assistance system. The brakes will then only function with increased brake pedal pressure.
What to do
Consumers should contact an authorised BMW motor vehicle service centre, or call the BMW Group Australia Customer Interaction Centre on freecall: 1 800 813 299.
Defect
Engine oil from the brake vacuum pump may enter the brake vacuum line, possibly allowing oil to enter the brake booster.
