2012 A8 Headlight Issue

[Welshman]

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.

I'd recommend a diagnostic check to see if any fault codes flag up. Could be an issue with the modules or ballast.

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.

This could be the issue then. I'd recommend a professional diagnostic check or get an auto electrican to take a look
