Interesting! So, you reckon it's definitely the air sensor then? Was it obvious when you looked at it, or did the garage have to diagnose it?

Yeah, sounds very similar. I didn't visually see anything wrong with the old temperature sensor, but the error code pointed to it. I'd suggest getting it checked professionally to be sure, but it's a likely culprit. A faulty IAT sensor can definitely cause those symptoms.

Got it sorted. It was indeed the intake air temperature sensor. New one cost me 155€ fitted. Runs like a dream now, thanks for the help!

I had a similar issue with my Tarraco, although mine's a newer model. Check engine light, sluggish performance... sound familiar? Could be the IAT sensor. Think of it like this: the engine is trying to breathe, and the sensor is telling it how much air is really there. If that temperature reading is off, the engine gets confused.
