I have a situation with the rear wing not working. It does not move when pressing the button and when I reach 75 mph.


I little background on how this situation started. I brought this car recently. Is a 2006 c2 997. When I purchased the car it had a fixed wing installed but the owner had the original wing. So I switched the car to its original state. When the original wing was installed it was inoperable, it didn't move when pressing the dash button. The following things have been checked:

1. We feed 12 volts to the wing on the wire harness and it moves up and down. So it is not
the motor.

2. The fuse was checked and was good. To my understanding there is only one fuse . Am I correct?

3. The spoiler button was switched with another and did not work either. No light appears whe pressing the button.

4. The computer was coded to indicate that the rear wing was installed.

I do not receive any errors regarding the wing but I do have an error message "check raised brake light" and my third brake light is not working. It might be related but I don't know.


Any help will be greatly appreciated.

 

Sure sounds like from the testing you've done that the coding in the car is still setup for a fixed wing. If the active Aero is enabled and the wing didn't move when it was supposed to, you should get a "spoiler failure" message on the dash. If I recall, when changing my c2s from the fixed RUF bi-plane wing to have active Aero, there were a couple different parameters that needed to be changed, but I don't recall if they were in the same module or multiple modules. Maybe check a couple of the TT wing on non-turbo car DIYs that have been done and see if there are coding screenshots in it.

Also, does it look like your rear wiring harness into the engine bay has been tampered with at all?

 

Looks like you got essentially the same info from the Rennlist thread you posted on the same issue so you should have a place to start.
