Exactly the point I was making. How do you feel when someone comes in for a code read then takes it away to get repairs done cheaper. Would be interesting to know EXACTLY what Audi dealer told him. Doubt that will ever come out because he may not have listned or been disinterested, most main dealer customers do not want technical explanations, just a fix. If he is reading this he will probably go to yet another fast fit for a cheap cat, soon the whole car will be poor quality parts.
