problem z otwieraniem tylniego spoilera

[ICE]

Ja wyczytałem na necie że też miewali taki problem jak Ty.
Rozwiązali go brutalnie. Na postoju gościu przycisnął przycisk od podniesienia spoilera po czym prędko pobiegł na tył samochodu i palcami pomógł mu się podnieść. Czynność powtórzył i problem znikł.

Jak to nie pomaga to moduł komfortu Ci padł.

Note: in readiness, have the boot open (but lowered, not raised 'vertical').
1. Press button on the console to raise spoiler.
2. Quickly go to the boot - you may here the motor attempting to raise the spoiler - and raise the hatch approx few inches. Gently rock the spoiler with your hand from the accessible side edge. Spoiler should raise automatically.

Audi designers used the 8J spoiler as a sought of non electronic telltale (excuse the pun)

To quote Pg 39 of the 2008 TT Training Manual Electrical system and Comfort System Electronics

System Malfunctions

"The rear spoiler is extended if any one of the following faults occur:

-Comfort System Control Module J393 does not receive a road speed signal

-J393 is unable to receive any CAN messages.

- Implausible signals received from switches F135 and F136

- Less than 10.5 Volts at J393"


Switches F135 and F136 are pins of the centre console rear spoiler switch

So it appears that your Comfort System Control Module is the most likely culprit.

Having said all that the rest of the symptoms are consistent with a flat battery in a TTS
