Terrible experience! I called Audi Assist out as my car was shuddering, overheating and lost power. The mechanic informed me that it was an electronic thermostat and to book it in under warranty. I booked it in and informed the service centre what Audi Assist had told me. I had taken it to the nearest garage (not an Audi garage) and they had inadvertently reset the fault indicator, although the fault was still there. By the time it was looked at the fault was no longer showing, even though the car was still not running correctly. I asked them if it would be logged as a fault, which I was told it would be, as the warranty was about to run out. Surely enough four weeks later the same thing happened but I was told that because it was out of warranty it was not covered and I would be left with a £1600 bill. After contacting Audi UK (who were useless and informed me that it was nothing to do with them as Audi, Slough were a franchise and as such they had no power/authority over them) they offered me a 50% reduction which I was unhappy with but accepted as I needed my car back. The staff were deceitful (one actually was proven to have lied to me when I replayed the recording on the telephone conversation) and I always felt that there was little customer service apart from the Aftersales Manager, Michael, who is very good at his job even though I didn't get the answers I wanted. I have owned four Audis but will not be purchasing another one.
