Peugeot 5008 engine stalling and power loss

My 2009 Peugeot 5008 with a gasoline engine has a check engine light and sometimes stalls at idle. It has 299236 km. I've also noticed reduced power. I suspect the fuel volume regulator, maybe a high-pressure pump issue. Anyone seen this?

Hey! I have a 5008 too, and that sounds familiar. I had the check engine light, and the car felt like it was gonna die on me at stop lights. Did it also kinda feel like it was misfiring? Or like, hesitating to accelerate?

Yes, there's a hesitation upon acceleration, suggesting a misfire. Could you give me more details on how your issue was resolved?

Yep, sounds like the same thing! Honestly, I didn't mess with it myself. I took it straight to the shop. They said it was something with the fuel injection system, something about the high pressure. Cost a pretty penny but runs like new now!

Based on your input and further checks, it's a defective high-pressure fuel pump and needs replacing. Repair cost is about 1510€. Thanks for confirming my suspicions.
