RCZ exhaust temperature sensor fault

I had something similar with my RCZ. Is it throwing any specific error codes? Mine was the exhaust sensor too, and those symptoms sound familiar.

Yeah, it's showing a fault with the exhaust temperature sensor. Was it a pain to fix? Did you notice a big difference after getting it sorted?

Okay, with that error code, it's almost definitely the exhaust sensor. I'd say get it checked at a workshop. They'll be able to confirm if it's a leak or just the sensor itself. It made a huge difference once it was fixed, power was back and fuel was way better.

Cheers for the advice! Took it to the shop, and you were spot on. It was a faulty exhaust temperature sensor thanks to a small leak. Got it sorted for 265€ and the car is running like a dream again. Really appreciate the help!
