I've had a generic scanner and a vagcom scanner on it and it shows zero error codes. Only problem is that when trying to communicate with the headlight controllers directly returned an unable to communicate message.

I have a 2012 A8L and my high beam's aren't working. I have DRL, Indicator and dip beam all working but the high beam will not activate. I have fitted new H7 Bulbs and still nothing. The high beam appears on the dash when the stalk is pressed but the lights do not activate. It is the same on both headlights so its causing a headache trying to figure it out Any help would be appreciated.
