Spoiler fault..

[Mooogie]

The joy.. every time I start up, I get a warning ding and message that there is a malfunction with the rear spoiler. I don't think it is related to my alternator about to fail (again) since my OBD11 is showing 14.8v charge to battery (when engine running, so this looks fine).  Audi USA have a TSB (https://static.nhtsa.gov/odi/tsbs/2022/MC-10209108-0001.pdf) that the spoiler motor brushes don't have enough pressure and are replacing under warranty up to 50k miles. No such info seems to be available in the UK.. plus I'm well outside my warranty now. OBD11 seems to suggest the spoiler stop switch see below? Anyone had this issue, know where the switch is and if replacing it cures the problem?

Thanks!

my OBD scan gives this..

Mine only does it on the motorway only, whilst it’s up when you slow down it bleeps with the rear spoiler fault. Then it stays up until you park up and shut the car off completely and only then you have to press the button to drop it down, it won’t go down automatically.

Like you I'd suspect the switch.

Well, 2 months later and it has decided to just start working again... without me doing a thing! With the manual control to put it up, I've greased the hinges and pivots, so wondering if it had somewhat seized for a while, and then unstuck itself...

Fingers crossed it stays fixed 🙂
