Hello all I have just bought an 2006 Audi A4 3.2 as a projected I am having a few problems tho. The first one is it was only running on 3 cylinders new coil packs fixed most of. it but I cannot use the obd plug as I get a message saying it’s down I am using snap on souls pro never had a problem with it on any other car I also tryed a cheap reader it s saying make sure ignition is on when it is. The car is completely standard from the factory but was say for 2 years I put a new battery on her and checked oil coolant etc and made sure it was not seized
it does run but lumpy I just can’t figure out the obd port issue any advice would be fantastic thanks dan
