Peugeot 5008 engine stalling and power loss

I'm having trouble with my 2019 Peugeot 5008, gasoline engine, with 91622 km. The check engine light is on, it stalls at idle, and engine power is reduced. I suspect a defective fuel pressure regulator, possibly triggered by an error after a recent fuel filter change. Has anyone else seen this?

I have a 5008 and had similar symptoms: check engine light, stalling, and power loss. Did you notice any pressure drop or impact on fuel efficiency?

Yes, I have noticed a slight pressure drop. Fuel efficiency seems normal for now. Were you able to resolve the issue? What was it?

Yes, the symptoms sound very familiar. I'd recommend a workshop visit. The error code pointed to the fuel pump in my case, but the fuel pressure regulator was faulty.

Thanks for the advice. It was indeed the fuel pressure regulator, as suspected. The repair cost 45€. The check engine light is off, and the car is running smoothly again.
