Mini Cooper exhaust back pressure sensor issue

So my 2013 Mini Cooper is throwing a warning light in the speedometer, and I'm seeing some smoke when I accelerate. Did a quick vehicle diagnostics and it points to the exhaust back pressure sensor. Plus, the DPF won't regenerate. I'm thinking it's a defective sensor messing with the exhaust system and emission control. Anyone else run into this?

I had something similar happen with my Mini. Is it impacting your engine performance?

Yeah, the engine definitely feels sluggish, especially when accelerating. Also, I tried forcing a DPF regeneration using vehicle diagnostics, but it won't start. Was that also the case for you?

Sounds very familiar. I had the exact same symptoms. My mechanic confirmed it was the exhaust back pressure sensor. I'd say get it checked out by a workshop to be sure.

Just wanted to update you it was indeed the exhaust back pressure sensor. Got it replaced for 245€, including labor and the part. The warning light is gone, and the smoke is gone. Thanks again for the heads up!
