I brought my Audi A3 to the Audi Dealer to fix an oil leak. I was told that the oil pan and valve cover gasket needed to be replaced for $6,000. Based on reviews, I went to Performance Autowerk for a second opinion, Rich said the repair would be $3,300. I agreed to the repair. Once under the hood, Rich determined that the valve cover gasket didn't need to be replaced. Rich called me and, based on his input, I declined the gasket replacementsavings of $1600. I can't imagine another auto shop doing the same. Based on his honesty and the quality of his work, I would wholeheartedly recommend Rich and Performance Autowerk in Dublin, CA, for all your German auto repairs.
