Corolla active air flap fault

I'm experiencing an active air flap fault with my 2023 Toyota Corolla Hybrid. The check engine light illuminates intermittently, and I've observed engine overheating during prolonged operation. My Corolla has 162370 km on the clock. Initial diagnostic scans point towards a defective electromechanism controlling the grille shutter. Anyone else encountered this?

Interesting. I had a similar issue with my Corolla – it's also a hybrid. Check engine light and all that. Did the cooling system seem affected? I'm wondering if it is the same issue I had.

Yes, the cooling system definitely seems impacted, particularly during slower speeds or when idling. Radiator fan seems to be running more often than usual. Was your issue definitively traced to the air flap electromechanism?

Yep, same symptoms here, and after a bit of fiddling around, and eventually having it properly diagnosed at a workshop, it was indeed the air flap electromechanism. I’d suggest getting it checked out by a qualified technician; could save you some headaches.

Thanks for confirming. Based on your experience and the diagnostic scan results, I'll proceed with replacing the electromechanism. The estimated repair cost is around 590€, which seems reasonable. I appreciate your input.
