I'm experiencing the same problem, by changing the clock spring and steering wheel controls the problem went away for you. Where did you get the parts, did the dealer do it or you?I too had this problem. It also conincided with the steering wheel controls not working. After a lot of mucking about i spent a pile of money on a new clock spring and steering wheel controls and the problem has gone away. We also tweaked the microswitch on the header rail but I doubt that was it.
