I recently had the turbo aerokit rear spoiler installed. Unfortunatley, Porsche does not provide any instructions for how to eliminate the spoiler failure warning. We can erase the code in the computer, but it just comes right back after the car is restarted (and again after each time you go above or back below 60 mph).

Does anyone have DIY instructions for eliminating this problem. Basically it will involve a minor amount of rewiring. I'm sure someone out here has done this before... We could sure use the help! (Of course I could always pay a P-car dealer a couple hundred $ to switch a couple of wires... but where's the fun in that!)

Thanks in advance,

 

I think you are suppose to use a paperclip ?

Well, the next step is to find out if (a) I got one and the body shop lost it or (b) the harness was omitted from the box at the factory.

As for now, Cobra06 was nice enough to provide the wiring splicing solution over on Rennlist. In case anyone else runs across this issue, here is the solution (for pretty much any fixed wing spoiler):


Unplug the harness on the right side of the engine deck.
If you look at the harness from the rear, with the lock at the top;
start at the bottom row.
thick brown and thick black = fan motor
next to them a thin red/blue and brown/red =lamp
next is a single thin wire for brake light power
top row; BLANK, then first is a single wire for the brake light(signal), next a green gray spoiler switch wire, next yellow/green thick spoiler motor (positive) , next thin gray/brown spoiler switch, last thick green/blue (ground)spoiler motor.

Unplug the thick green/blue, by pulling it out of the harness (ground for motor)
jump the spoiler switch wire, thin gray/brown with a spoiler power thick yellow/green. did it by using a paper clip
No light no hot spoiler motor wires
Usual disclaimer

 

Let us know how it turns out as I might be aerokitting my dad's TT here....

 

It worked fine. However, come to find out, the body shop later found the correct wiring harness in the box that the spoiler came in! Arggghh. So, as it turns out, we did not need to rewire the existing harness. Bugger!
