first off hi to everyone new to this site but not the vag scene as i own a golf mk4 1.8t also i have done some searches etc but just want some decisive answers... reason i need help is the wife as got an a3 1.9tdi sport on a 51plate,had the overboost code on vag com so had turbo cleaned with innotec turbo cleaner ,1 week later back to limp mode but then went and came back several times...i have noticed there is a lot of oil around the egr valve and could probably do with a clean just wondering if i need vagcom when i put it back on or does it sort itself out is there a gasket that could break or will it be ok to just take off and clean,want to try and eliminate easy cheap fixes before changing n75 etc so any help greatly appreciated thanks in adavance also is this a pd engine its the 110 sport atd i think cheers ppl

Yep its best to clean the egr and replace the gasket, but it doesnt need to be set up on vagcom.

The overboost code is probably still the turbo though. Innotec doesnt clean it as good as physically taking it off and cleaning it. Its a big job though taking them apart.
