Just looking for bit of advice, I've have a juddering issue in higher revs and I'm looking to get the car in to Audi for a £96 diagnostics check. The girl on the phone said they don't just plug it in they will find the problem, just wondered if anyone else has used this and is the Audi check worth the extra over me paying some one with vagcom to just read the ecu? ... I'm not stealer savvy. Cheers
