someone suggested I should replace the SZL "clock spring" on my MY12 r56 N18 since i have the Brake/DSC light on.
For those that have replaced it,
1) what were the symptoms you had that made you change it?
2) did you have to have a dealer do it or program it for you?
3) how much did it cost?

Thanks so much!

 

usually you would need to pull the codes for that system and see what's wrong. did you rule out that abs sensors? did you get a live data reading on the SZL module?
