2003 Turbo wing failure - Help

[lisa]

Hi, I have a 2003 Turbo and the tail wing has failed. When the car reaches the correct speed the failure notice comes up. The wing still raises when the manual button is pushed but not on it's own. Anybody had this happen?
The two hydraulic motors that appear to drive the wing are leaking.
I really would love to hear from someone who has fixed this themselves as the dealer wants a stupid amount of money to fix.

Thanks
