Mini One Overheating Issue

Active air flap issue on your Mini One? Overheating and a check engine light definitely point to cooling system problems. Did you perform a diagnostic scan to confirm the fault code? Could be related to the thermal management system.

A diagnostic scan does point to the active air flap. Is it likely the electromechanism is defective?

Yeah, the electromechanism is a common failure point. If the diagnostic scan points directly to the active air flap and you're seeing overheating, that's likely the culprit. Probably best to take it to a shop.

Thanks for confirming my suspicions. Ended up taking my Mini One to a shop, diagnostic scan confirmed the active air flap was faulty. Repair cost me around 590€. All sorted now.
