Windshield wipers defective message

Got the "windshield wipers defective" message, but everything seems to be working fine.

Forum search proved fruitless.

Thoughts?

Thoughts?

Can you put them into the service position via the MMI? Are they parking in the proper spot or are they going beyond the normal position into the cowl tray when parking (i.e., too low when parked)? Have you changed the wipers recently, had a windshield replaced, etc.? Any unusual noises when the wipers are operating? Do the wipers work on all speeds, including intermittent?

Also saw a thread about a Q7 with the wipers defective message at this thread. The guy got this on a scan:

VCDS says

00908 Control Module for Wiper Motor
03 Mechanical Failure - Intermittent

Found one more piece of info here. Shows an icon of a windshield with a wiper. It states: "This symbol in the electronics for the windscreen wipers. Take the vehicle to a qualified workshop indicates a malfunction in the electronics for the windscreen wipers. Take the vehicle to a qualified workshop to have the windscreen wiper system repaired."

Lastly, here's a page showing the indicator lights for a 2016 S4.. Couldn't find one for a 2012.

Let us know what you find out!

Was thinking it could be the rain sensor as that was the only thing I didn't test. Fortunately, after two days of being on it didn't come on today for my drive home from work.

Will swing by my indy shop when I'm near them and have them check to see if it threw a code.

So far so good (for now)!

Had a friends s4 give this message. Cleared it, never came back. No idea what had caused it.

Message didn't come back, but wipers stopped working two days ago. Replaced the wiper motor including the attached control module. All good now.
