XC60 engine power loss

Hi, I'm having trouble with my 2017 Volvo XC60 diesel. The check engine light keeps coming on, and I've noticed a significant drop in engine power, especially when accelerating. It feels like the engine is struggling, and fuel consumption seems higher than usual. My car has 219991 km on it. Could this be a faulty manifold pressure sensor, maybe due to a vacuum leak?

Sounds familiar! I had something similar happen in my XC60. Reduced power and the light were the first signs. Does it feel like you are driving with the parking brake on? Is the engine response generally sluggish?

Yes, exactly! It does feel like I'm constantly fighting against something, like the parking brake is partially engaged. And the engine response is definitely sluggish. What exactly was the issue with yours?

Yep, it was the manifold pressure sensor for me too. The garage said it was likely due to a large vacuum leakage somewhere. I'd get it checked out by a professional. It's probably a sensor replacement.

Thanks for the advice! Turns out you were spot on. Took it to a workshop, and it was indeed the manifold pressure sensor. Replaced it, and the car is running perfectly again. Total cost was 235€.
