Hi All,

Hoping someone here can shed some light on whats wrong with my car.

Have an a4 tfsii2.0 quattro, 56 plate. Long story short, we had our coil packs replaced on the recall thing Audi done 2months ago. About a month after the replacement the car runs rough on start up intermittently then possibly clears after a 5min run or stays for longer. It sounds like it has a miss and feels like a lack of boost, limp mode? No warning light. This can happen at anytime when hot or cold and can clear at anytime. I've done a small service on it since, swopped plugs/oils/filters as I was going to anyway. However, problem still exists and I thought I'd got a bad coil pack, my vagcom wont show me the memory. So the wife takes it back to the audi garage today and the mechanic had given me a print out of the events.

Now ideally I'd like to clear these but my vagcom isn't working at the moment. Just to see what would come back and to diagnose. I know seeing another thread that the evap problem has been resolved by replacing the n80 valve. However this thread didnt have the turbo boost fault. The mechanic advised the wife it might be a valve or something on the turbo. I need to confirm what part the mechanic mens but thought I'd pass it by here if anybody can add anything.

Any info would be great.

Thanks All.
