I was surprised the other day while driving by a beep and the simultaneous yellow light appearing on the DSC, BRAKE and ABS symbols.
When I turned off the engine for a while the light would go out, but then after a few minutes of driving it would appear again.
The car was at the mechanic a week ago, and he was working on the front left wheel, he also disconnected the battery during his intervention. I did some research on the forums and read some instructions on how to reset this behavior (turning the wheel clockwise the counter-clockwise to the extreme, or opening and closing all doors) but it did not yield any results.
So I went to the car electrician in order to run the BMW on the scanner. The moment of truth revealed three alarms:
- Front left wheel speed meter.
- Brake pad.
- Power interruption.
He told me there was something broken which needed replacement but I insisted on clearing out the alarms. He did that and I then drove it and the symptoms did not appear for a week, then they started appearing again and more frequently. As a last shot before the mechanic, I decided to do it myself and check the sensor. I removed the wheel, checked it out, re-fitted the cable connector firmly and that was it. No more orange lights, problem solved every since!
I guess the lesson learned here is that I should buy a scanner and make sure I clear the alarms each time the battery is disconnected or some sort of sensor or electrical component is replaced or refitted.
Needless to say that I have tested the ABS and DSC functionality, it’s all working like a charm.
