Mercedes V Klasse Diesel Engine Issue Resolved

My 2010 Mercedes V Klasse diesel is acting up. The speedometer has a warning light, and I've noticed reduced engine power plus smoke when accelerating. There's also a strong exhaust smell. Could this be DPF issues? It feels like the emission control is failing me.

Sounds familiar. I had something similar with my V Klasse diesel engine. I was experiencing reduced power and a weird smell too. Have you checked the exhaust back pressure sensor? That was the culprit for me. It could be giving false readings and messing with the DPF.

The exhaust back pressure sensor, huh? Where is that located, and is it something easily checked? I am not that technically savvy.

I am no expert either, but my mechanic said it's often near the DPF in the exhaust system. Honestly, I wouldn't try messing with it yourself if you are not comfortable. Best to get it checked at a workshop. Could save you from bigger diesel engine problems down the line.

Thanks for the tip! I took it to the shop, and you were spot on. The exhaust back pressure sensor was defective. Repair cost was 245€. All sorted now!
