Hello all, I cannot get data to this a5 I purchased and realized the diagnostic port has been tampered with. I tried rewiring, managed to get power to the scanner but gives an error saying it cannot read the data line. I am in desperate need of a picture of someone diagnostic port from behind. I have tried following wiring schematics and cannot understand them. A picture of the obd port of someone who has this exact car would be a lifesaver for me. I have gone to the junkyard and could not find an exact match.
