Mike and his Staff at BARtuning are the best VW/Audi Foreign and Domestic Mechanics in Houston! My 2001 GTI is purring like a kitten again. I was being "driven" crazy with the Check Engine Lights popping on. Mike replaced a series of vacuum hoses and valves and was able to diagnose a tensioner valve problem in the valve case supplying oil to the valve heads (layman's terms but you get the jest). He saved us catastrophic engine failure...which is always nice! My Touareg V6 also obtained an oil change at the same visit. (Hint: If your key FOB ever decides to die while trying to enter your Touareg, you will obtain a "Immobil Activation" message in your console and the alarm will blare loudly causing deafness. Make sure your Key FOB is water tight, has had its battery replaced and use the Start Engine Buttons to start the car.) Thanks again to Mike and his Staff at BARtuning for the service and tips!!
