Avantime Blower Motor AUC Sensor Issue

Avantime owner here. Sounds familiar. Does the auto recirculation seem off, too? The AUC sensor, sometimes referred to as a cabin air sensor, is a known culprit. It's used by BMW too, I think. Have you checked the cable and plug connection?

Yes, the auto recirculation does seem to be behaving erratically. When you had this issue, was it also due to a defective cable or plug connection, or something else entirely? I'm trying to narrow down the possibilities before I start taking things apart.

In my case, it was indeed a faulty connection. While you might be able to fix it yourself, honestly, it's a bit fiddly. Unless you're really confident, a workshop might be the best bet. Could save you some headaches.

Thank you for the advice. I took it to a local workshop. The cable connection was indeed the problem. The repair cost me 95€. Hopefully, this information is helpful for other owners in the future.
