S80 smoking exhaust back pressure sensor

Hey, I'm having a weird issue with my 2014 Volvo S80 (gasoline engine). I'm getting a warning light and it's puffing out smoke like a chimney when I accelerate. My car has 125683 km. I'm guessing it is something related to the exhaust system. Has anyone dealt with anything similar? Could it be the exhaust back pressure sensor?

The problem was suspected to be related to the exhaust back pressure sensor. After taking the car to a workshop, it was confirmed that the sensor was defective. Replacing the sensor resolved the issue, and the car returned to normal performance.

I had something similar happen with my S80. Is it impacting your engine performance at all?

Yeah, the engine definitely feels a bit sluggish. Does that confirm your suspicions? What was the fix?

Yep, sounds like the exhaust back pressure sensor to me. I ended up taking mine to a workshop. It's not something you want to mess with if you don't have the right tools and know-how.

Thanks for the heads-up! I took it to the workshop, and you were spot on, it was a defective exhaust back pressure sensor. Cost me 245€ to get it replaced, but now it's running smoothly again!
