Peugeot 208 Diesel Stalling Idling Power Loss

My 2014 Peugeot 208 diesel has a check engine light, stalls when idling, and has reduced power during acceleration. It has 103089 km on the clock. I suspect a faulty fuel pressure regulator, possibly from an error during my last fuel filter replacement. Any guidance?

I also own a Peugeot 208 diesel and had similar symptoms: check engine light, rough idle, and power loss. Has fuel efficiency been impacted? Investigate the fuel rail pressure sensor, in addition to the regulator. Any unusual noises from the fuel pump?

Yes, I've noticed a slight decrease in fuel efficiency. I haven't heard any unusual noises from the fuel pump, but I'll listen more closely. Could you share the circumstances of your similar issue and how it was resolved?

My symptoms were almost identical. After basic checks, I took it to a workshop for a detailed inspection. They confirmed a faulty fuel pressure regulator. Given your symptoms and the recent fuel filter change, get a professional assessment to prevent damage to other components.

I took it to my mechanic. The diagnostic check confirmed a defective fuel pressure regulator, likely due to an error after the fuel filter change, as I suspected. Replacing the regulator (costing 45€) fixed everything. Thanks!
