This is the first time we had our car (1998 A6) serviced by anyone but Audi. We had several issues including a Check Engine light. One of these issues was an electrical issues that was intermittent and only happened 4-5 times a year. There was also an issue with the washer fluid system.
The service was well run and reasonable in price. The communications between the shop and me was very good. They resolved the Check Engine light, replaced the front brakes, replaced the washer pump and tank, changed the oil and attempted to fix the electrical issue.
The only issue was a delay in getting the parts for the washer system. That took two days to get. They did install it right after the parts arrived and that was well done.
I would recommend them to anyone who asks.
