Take the slip ring out and clean the contacts + inside the slip ring first, i had the same problem when i first got my cupra and a good clean done the trick but you will have to clear the error code with vagcom afterwards if i remember correct
Hello, I know it's been a while since you wrote this but today I took off my slip ring when I fitted a cruise control kit but I moved the ring and dont know if I'm 360 out or worse even more out, just wondering are there just contatcs and tracks inside it or worse wires so it can be turned to far so can snap if you catch my drift!?
Regards,
Rob
