Hi guys, I have recently purchased a new chrome headlight switch for my S3 2007. This new switch contains DRL as well whereas my OEM one did not. The new one fits perfectly, all lights are on apart from the DRLs. I suspect there is some coding that needs to be done via VAGCOM. Any ideas as to where to look in VAGCOM about this? P.S. I can use your advise as my local AUDI garage could not be able to resolve this issue. Cheers!
