V90 Air Flap Fault Overheating

Sounds familiar! I had a similar problem with my older Audi A4 a while back. Check engine light and overheating, also pointed to an air flap issue. Could be a defective electromechanism. Was the diagnostic scan specific, or just a general air flap error?

The scan was pretty basic, just flagged it as an 'active air flap fault.' Nothing more specific than that. How did you figure out what was wrong with your Audi? And what was the fix?

With the Audi, it turned out to be the flap motor itself. Needed replacing. Given the symptoms and the error code, I'd say your Volvo is probably having the same issue. It's probably best to book it into a workshop to have them take a look.

Thanks a lot for the advice! I booked it in with a local mechanic, and you were spot on. The flap motor was defective. The repair cost me 590€, but at least it's sorted now.
