with my Turbo R rear wing the wing mechanism works fine but the warning light now pops on, anybody else have similar experiences before I get the dealer to sort it ?

 

I have the RUF wing............it is impossible that this could cuase any warning light to go off..... All you are doing is replacing the an exterior part? No wiring harnesses touched or anything? How would the Cars computer know if you had the ruf wing added, strosek wing, or factory ? It doesn't - this is an internal issue that would have happened with your stock wing - take it to the dealer

 

- You made me think about this objectively and when I looked at the car today in the daylight the left strut was rising faster than the right and so this caused the warning light. I used some silcom spray on the slow strut and that solved the problem. Previously l had been on vacation for 3 weeks. You saved me a dealer trip and bill !

 

that should read
