Hi Everyone - our 2002 Audi TT is having some issues that only appear when the the headlights are being switched to bright or down to dim. We have experienced the following:

1. Radio cuts out and comes back on.
2. Instrument cluster dials drop and then go back to original position.
3. ABS and ESP lights come on and go off.

We have no loss of power or anything else. Any suggestions on what it could be and or how to fix it would be much appreciated.
