Thanks for the quick reply! Was it difficult to diagnose the sensor issue? Did you replace it yourself or did you need to take it to a shop?

I had it diagnosed at a shop. I wouldn't recommend doing it yourself unless you have experience. The sensor might be difficult to reach and you need specific tools to check the readings. I recommend you go to a workshop for checking. It cost me around 250€ for a new sensor and the repair.

Okay, thanks for the advice! I'll take it to a mechanic to have it checked. Seems like the sensor is the likely culprit. The repair set me back 245€, sensor was indeed defective.

Sounds familiar. I had a similar issue with my old Opel Astra. Same symptoms: warning light and smoke. In my case, it was also the exhaust back pressure sensor. I would check the sensor first.
