BMW 328I conv. Break Light signal reset , break pad wear signal

I have a BMW 328I, 2009 and changed the breaks by a mechanic recently. The brake light sensor and the "break pad wear indicator" signal remmain on, I looked for advice only and Tried to turn the ignition on so that all the dash lights are on , and not start the engine and leave on for aprox 45 seconds the brake pad warning lights should have gone out, but they didn't. Do you know what I should try next?

I will start with the obvious question and ask why you went to an independent mechanic? Is the car already out of warranty? And did the mechanic put a new wear sensor in?

To get rid of the warning you need to reset the maintenance indicator. If you search this site, there is a writeup of how to do this, it basically involves holding down the mileage trip button before starting the car and then flipping through and finding the brake system you worked on and reseting it.

The brake (break) pad sensor is just a wire that completes a circuit to ground when the brake (break) pad is very near the rotor - the wire touches the rotor.
