Hi lads !
i got very weird issues with ma audi
1. its no check engine light when i turn egition on!
2. diagnostic gear cant communicate with ecu all other systems works ok feels ( i mean i can get codes from other systems)like someone cut k-line wire some where lol coz car got problem on high revs turbo kics off and after restart its ok again im been told its map sensor but im not sure now coz i can get codes from ecu!
maybe some got similar issue? or any idea where to start looking ?
thanks
