I changed my rear brake pads on My E92 2 days ago and drove the car for the first time since today. All was fine until I reset the brake pad service item in the Condition Based Service menu. After doing so the miles to the next brake pad change indicates blank on both front and back, I may have reset the front brake pads service also accidentally, and the dash brake warning light is on along with the "car on a lift" fault indicator.
Searching online it seems that if you reset the brake pad service CBS items with a partially worn brake sensor installed this is what happens. Someone stated that disconnecting and reconnecting the pad sensor at the juction box in the wheel well may clear the fault, another workaround online is to disconnect the pad sensor and short the 2 terminals in the sensor socket and then reset the CBS. I decided I would try disconnecting the front pad sensor today as you can access it (with difficulty) without removing the wheel. I knew there was only one Sensor per pad front and back and I presumed the front sensor was on the pax side like the rear sensor. Anyway I ended up disconnecting the ABS sensor instead and after reconnecting it I now have ABS and DTC warnings as well as brake warnings.
I am going to take the wheels off tomorrow and try to reset the pad service CBS with the sensor terminals shorted, Will this clear the ABS fault also does anyone know?
