Do you have any further information on this? I have a problem with my trip meter resetting everytime the car is shut off, might have something to do with this.madm5 said:I'm a very new M5 owner but i understand that when the service lights malfunction it's usually due to dead rechargeable batteries soldered on the circuit board. They're AA size and any reasonably competent tech can resolder new batteries in place for less than the cost of a replacement board.
-Thanks!
