View Full Version : Atw a4 rough idle and acceleration problem

04-15-2017, 03:14 PM
I need help! My cars been in the shop twice with them literally not even driving it once, and they did nothing but replace plugs and my valve cover gasket, I've replaced plugs, maf, and my dv, this last time replacing plugs it started running almost fine now is back to "stuttering" under acelleration almost like a cool wire or bad coil, or a boost leak, I get no codes since replacing the dv and don't even remember what they where! And realized the other day when I turn my Ac on it gets worse and the car almost won't even run l... I'm so lost, oh and the battery has been replaced aswell

I just bought a vag com, waiting for my patch to be emailed, but in the meantime I'm kindof lost with it, it's a bit above my head as far as how to use any of this info

Any codes? Vcds lite is free. Sounds like a map sensor problem... had one last week.
