Mini Cabrio rough engine running

My 2011 Mini Cabrio's engine is running rough. The check engine light is on, and I feel like there's reduced engine power. The error memory mentions something about the intake air temperature sensor. Could a defective car sensor really be the cause?

Sounds like a faulty IAT sensor. I had similar engine issues with my Opel after the air temperature sensor went bad. The temperature reading was off, which messed with the fuel mixture. Is the check engine light on?

IAT sensor? What exactly does air temperature have to do with engine issues?

The IAT sensor tells the car's computer the air temperature coming into the engine. This air temperature data is used to adjust the fuel mixture. If the temperature reading is wrong, it can cause all sorts of engine issues like rough running. Better get it to the workshop. The eventual repair cost me 155€.

Just a quick update. The intake air temperature sensor was indeed faulty. Replaced it, and now everything seems fine. Thanks for the advice!
