Hi. I have a 2012 A3 1.4TFSI. It’s a cat C. The head lamps were originally bi xenon and have been replaced with standard halogen. I have warnings coming up on the dash regarding, error on adaptive motor, main beam not working for more than 5 seconds. 
What can be done to resolve the problems? Best Regards. 

Possibly you need to code with vcds and tell the car it has halogen not xenon , also they may need some rewiring .

 

Tried vcds. No halogen option. Thanks for input though. 

did you check in body control module , long codding ?

Also try 

Open Central Electrics module
Click Long coding helper
Byte 21

The local independent audi/Vw tried coding which I assume is vcds. They went through it with me watching on. . 

You can retrofit xenons to halogen a3 so there must be a way to code halogens 

My thoughts exactly. Will keep researching. Thanks
