Since having the ignition barrel and starter motor replaced on my 1997 1.9 tdi A4, I have an issue with the headlights in that when I indicate LEFT, the main / high beams come ON.
Note: this only happens when the headlight switch is in the 'on' position (i.e. normal lights are on) and only when indicating left. The normal operation of both the indicators and the headlights (ordinary and high beam) and the battery charging is not affected. Also, the fog light button doesn't illuminate - I don't know if this is connected?
I've been told this is likely to be an 'earth' problem, but I was hoping someone with some expertise could help me with where to start looking? I don't know if any of the components I have changed are connected to the lights?
