I have a Q5 3.0Tdi 2014. A dash warning has appeared stating "Main Bean Assist System Fault". I have scanned the car with VCDS and a fault code "03395 Control module for High Bean assistant"

Has anyone experienced this problem and how best to fix it.

Thanks

Have you manged to resolve this yet?

Does your high beam assist still work? Have you tried clearing the faults to see if it comes back. Try cleaning the sensor area on the front windscreen by the rear view mirror. It could be a faulty sensor, and replacing the whole mirror with sensors might fix it - see here
