I own a 2005 VW Touareg that was driving very rough, and my check engine light came on. Desert VW quoted me almost $2000 for a new transmission, even though they weren't even sure that was the problem. Pacific Auto Care diagnosed bad spark plugs and a hole in the vacuum hose. It cost me less than $500. I was thisclose to letting Desert VW try and fix it -- so happy I went to Pacific! My car now runs perfectly.
