I have a 2005 R53 with the Chronos gauge package. The brake pad light came on last week, so I went to do the brakes today. I pulled the wheels off and all of the brake pads are still in great shape. They were replace 10,000 miles ago. I went ahead and plugged new OEM front and rear sensors in, but the brake pad warning stays on.

I do not see anything else that could be wrong. Is there something that needs to be reset on the cluster. I searched and only found the 2nd Gen information on resetting the cluster. Any help would be great.

 

IF is a sensor problem, you reset GEN1 sensors by turning the ignition to ON but do not start ... for 30 seconds.

Then start and the warning should be cleared

 

I had an issue resetting my warning light after a brake job some time ago. The electrical resistance of the new sensor was just a little too high for the system to automatically reset.
Take the old sensors (if you haven't thrown them out yet), cut the sensor off the end and splice the two wires together. Plug them into the harness on the car and turn on the ignition. This should reset the light. Turn the ignition off and plug the new sensors back in.

 

I ran my R53 through a car wash and the yellow brake light came on. I put the ignition key in the number two position for 30 seconds and the yellow light cleared. I was sure the brakes are fine because they were just serviced 3000 miles ago. The wheel bright stage of the car wash must have tripped something.
