While traveling throughout Eastern shore on business the infamous check engine' light lit up approximately 150 miles from the nearest Audi service shop. Understanding this was not critical, I stopped for lunch and to plan my next move. The owner of the restaurant recommended Mark at Bridge Auto Service. "But you don't understand, this is an Audi, and most non-Audi service guys cringe when asked to take a look", I remarked. "Try him out, he's good!" I was met with respect and within 5 min, in the parking lot, the problem was identified, dashboard light disappeared and Mark told me to have a nice day. If the light comes on again, bring it in to Audi. Now, this businessman deserves kudos.
