Hello everyone I’m new to the forum I own a 2014 Q7. So back in May the wife was driving and car went into limp mode so it went to first garage and had a new egr valve fitted car still in limp mode so went to another garage they had it a good while they didn’t know what was up with it. So I phoned My local Audi they said because it’s been to another garage they were not keen on looking at it. Now it’s in an Audi specialist’s been in there 5 weeks and all I have been told it’s a real head scratcher problem and can’t put his finger on it. Has anyone had a similar problem or heard of a problem like this thanks for looking. Pete
