Fiat Fullback DPF Pressure Issue

I'm having a strange issue with my 2020 Fiat Fullback diesel. The engine warning light is on, and the power is noticeably reduced. Plus, there's smoke when I accelerate and a strong exhaust smell. The diagnostics say it's a 'Diesel particulate filter exhaust pressure too low' error. Could this be the exhaust back pressure sensor? I'm at 50866 km.

Sounds familiar. I had almost the same problem with my Fullback. Same symptoms – the warning light, sluggish performance. Did you notice any difference in fuel consumption or any weird noises from the exhaust system?

Fuel consumption seems normal, and no strange noises. Just the smoke and the smell, plus the error code. Was it definitely the pressure sensor in your case?

Pretty sure it was. Although I tried a few things myself, I eventually took it to a workshop. They ran some proper tests and confirmed the pressure sensor was faulty. Best to get it checked professionally; exhaust systems can be tricky.

Thanks for the advice! I'll book it into a garage. Turns out it was indeed the exhaust back pressure sensor. Repair bill came to 245€. At least it's sorted now!
