Looking for a bit of coding help. I have fitted a flat bottom steering wheel out of a TT to my 2005 A3 sportback, I also upgraded the slip ring (1K0 959 653 D) and steering ECU (8P0 953 549 F) after discussions with Mike Foster on here. thanks Mike. Anyway, I now have a few issues which I would assume are down to the lack of coding. Airbag light on, steering wheel light on, skidding car light on. The steering is now heavy, horn doesnt work, multi function doesnt work, illumination doesnt work. I have someone who has VCDS but he was asking what the codes would be. Thanks in advance.
