XC40 Rear Ventilation Flap Fault

Rear ventilation flap, huh? Sounds familiar. I had a similar issue on my old BMW 3 Series. The automatic climate control went haywire with the same symptoms: error code and warm air. Does the Volvo use those little flap actuators for the rear vents?

Flap actuators? I'm not sure. Where were they located in your 3 Series? Was it a pain to get to them?

Yeah, it was the flap actuators. Not fun to replace, being buried under the dash. If the Volvo's anything like my old car, it could be a similar story. It's probably worth getting it checked out by a workshop to pinpoint the exact problem with their diagnostic tools. Better than throwing parts at it.

Appreciate the insight. I booked it in, and it was indeed a dodgy connector on the rear ventilation flap actuator, just like we suspected. 95€ later, it's sorted! Glad I didn't tackle it myself!
