Hello. sorry if this is the wrong section. Some help coding my rear lights would be great. I have a UK 2009 a4 avant with standard bulb lights. I have used the kufatec so wiring is all done. I cant seem to get the lights to work properly. I changed a few channels using some other forums/posts but even their coding does not do the job. any ideas guys would be much appreciated if you could inbox me it. Thanks
