I was working on a Audi A4 1.9TDI engine code AFN last week, I was concerned about the emissions being high and wondered if a fault existed besides the car having completed 207000 ++
I scanned for fault codes and none were recorded. I checked back door live data and found that the APP voltage would not increase while depressing the pedal, so I wondered how can that be given that the engine will rev up normally?
I pulled out the ECU and back probed the circuit, using a fluke meter the voltage levels were all correct and the APP works normal, so my question becomes;
Why is the Solus Pro providing false, incorrect data?
