If you read my link to another forum posted earlier in this thread, then the links from that i posted to a German forum. It seems under discussion in Germany that with the mk6 some seem to work error free by turning off the cold diagnostics option for the rear numberplate lights in VCDS but some it does not seem to work error free for that long... The cars that are coming out the factory with them fitted have a new software version 615 or higher so i wonder if theres an extra setting for them the old software does not have?
The crude way is to just fit resistors.
