I got issues (dont we all)
I have a 97 528i.

Issue 1. I recently had to change out a right rear speed sensor. It snapped off. To avoid taking the axle out, I opted to drill out the old one and put the new one in. Now...when I brake, there is a pulse in the brake pedal.

Could there be a piece of the old speed sensor still stuck in the wheel carrier? Is there an easier way to get at it rather than remove the entire carrier?

I Issue #2, when driving the car switches from D on the indicator to S 1 or S 2.. I have neither. What is the possibilities that this is the gear position switch on the side of the trans?

Thank you
