Peugeot 206 overheating active air flap

Hi, I've got a 2002 Peugeot 206 diesel with about 58000 km on the clock. Recently, the check engine light comes on and the engine seems to be overheating. I've noticed it especially when I'm stuck in traffic. Could this be related to the active air flap? Any ideas?

Sounds like an active air flap fault. I had a similar issue with my 206. Does the engine overheat quickly, and does it seem to struggle at higher speeds? You might want to check the grille shutter's electromechanism.

Yeah, the overheating happens pretty fast, especially in city driving. What exactly am I looking for when I check the electromechanism? Is it something I can fix myself, or should I just take it to a mechanic?

The electromechanism is often the culprit. If you're not comfortable with car electrics, I'd advise against DIY. I ended up taking mine to a workshop; they confirmed it was defective and replaced the whole unit. It's a common fault. Best to get it checked properly to avoid further engine damage.

Thanks for the advice! I took it to the workshop, and you were spot on - it was the air flap electromechanism. Cost me about 590€ to get it sorted, but at least the check engine light is off and the overheating is gone!
