Just a quick reminder. For optimum performance with your VW go by the manufacture service/maintenance cycle. I find that this is the best in keeping your valued VW vehicle on the road. Franco

Not trying to be a smart ass but that generally the best idea with any car.

Rocco,
Just trying to send some business your way! Many people do not even pay attention to their service manual until some kind of mechanical failure has occurred. Willing to bet most manuals have never even been cracked open.
