I was bummed to see this on my new-to-me 135i a few weeks ago. It turned out the brake pad sensor broke. The fix was relatively easy. It's always satisfying to work on a car.

I think car symbols are funny. Yes we all know that picture means it needs service because we know that is a lift its on but I would like to think that somewhere out there in this crazy world someone thinks they just won some kind of driving trophy.

Correction: it's always satisfying to work on a car and that car is cooperating.

I bought the part from Bavarian Autosport (BMW part, $30). I had my car on a lift, but jacking it up (use all safety precautions - jack stands, etc) will work. I removed the rear passenger side wheel. I removed the inner brake pad (easy, required a hammer and small punch to remove the retaining pins - I found a post on how to do it via Google) and inserted the sensor into the notch in the brake pad and reinstalled the pad. I put the wiring into the path of the old sensor. I did have to remove a few bolts holding the fender liner on, and plugged it into the spot where the old one was. I did this by removing the old sensor a bit at a time and putting the wire back in the fasteners as I went along. It took about an hour or so. It's easy.
