Help requied in diagnosing PDC fault code
I've had numerous issues with PDC in my A8.
I've replaced all front and all rear sensors, front ones still don't seem to work but they stopped throwing codes, i think maybe the speaker for the front ones may have gone?
With the rear ones I'm getting one code:
01549 Supply Voltage for Parking-Aid Sensor 29-00 Short To ground.
Could this be a wiring fault or maybe the PDC module in boot can be faulty?
