I fitted my cruise control kit today and then did the coding as shown here: http://www.audi-sport.net/vb/new-a3-s3-sportback-8p-chassis/131338-cruise-control-please-can-someone-check-coding-ive-found-correct.html To be honest, the VCDS pop up screens tells you what to enter anyway. Everything went smoothly and the coding was simple and worked a treat. I did get the ESP fault on the DIS, but this went off after driving a few metres. The cruise works perfectly and everything is good. I then ran a full scan using VCDS and it brought up a fault with the steering controller, saying 'Incorrect Coding'. I cleared the codes and went for drive before scanning it again, but the same error showed. Should I be worried about this fault code, considering that everything seems to be working perfectly? Is it just that the coding is correct for having cruise control installed, but the controller thinks the coding is incorrect for my chassis number because it wouldn't normally have cruise on it? (The parts were bought from Huntingdon Audi, who confirmed that my controller will accept cruise).
