Thanks for the quick reply! I haven't pulled the codes myself yet. I was hoping it was something simple before I had to get the OBD scanner. But it's good to know someone else has seen this on a Mark X. When you had the issue, was it definitely the active air flap causing the overheating? And was it an easy fix, or did you have to replace a bunch of parts?

Yep, sounds like my experience. I really think it's the electromechanism. I remember the overheating was pretty scary. To be honest, I'm not a mechanic myself, and after a bit of poking around, I decided it was best to just take it to the workshop. They confirmed it was a faulty air flap and replaced the part. Cost me around 590€, I think.

Alright, thanks a lot for sharing your experience! Sounds like I'm headed for the workshop then. Knowing it's likely the air flap and about what the repair cost was really helps. Appreciate the insight!

I had a similar issue with my Mark X a while back. Check engine light and overheating are definitely worrying. Was it throwing any specific fault codes related to the thermal management or air intake system? It could be a defective electromechanism of the air flap. Knowing the error codes would really help narrow down the possibilities.
