anybody knows how to reset the service light? is it only can be done by dealer?

 

The method i use is for the b5 but it should also work on your b6
1 Insert your key into the ignition.
2 Push in the odometer reset button, hold it in, and turn the key to the first click.
3 The display should read either "oil" or "service" if it does not, repeat steps #1 and #2.
4 To reset, push the clock adjustment **** the bottom of the tachometer.
5 Turn the ignition to the off position. When the ignition is turned back on, the display should be back to the trip odometer.

 

thank you! will try it later.
