Obd2 communication
Trying to help a friend diagnose his 2007 R56S car..... He had an aftermarket amp also an audio source eq some months ago...
After trying to get the car inspected it was determined that the obd2 port has no communication with the scanner.... tried to figure
this out tracing wires,,,, all lights, windows, door locks, sunroof is working which I believe is controlled through the footwell module.
The fuse box in the engine bay was checked and one of the relays is getting constant power with the relay removed.... Which it should be only
getting power on one side,,,,, The car also starts and drives without any problems..... could it be a fault in the foot well module?
