DS4 starting issues

I've got a 2014 Citroen DS4, diesel engine, with about 119k km on the clock. Recently, it's been a nightmare to start, sometimes it just won't. When it does start, it occasionally stalls, especially when idling. The check engine light is on, and the engine runs rough. I've also noticed higher fuel consumption. I scanned it and got an error code. I'm thinking it might be the fuel pump, but I'm not sure. Any ideas?

A 2014 Citroen DS4 with a diesel engine was experiencing starting issues, occasional stalling, a rough-running engine, and increased fuel consumption, accompanied by a check engine light. The problem was suspected to be related to the fuel pump. Upon further investigation, it was found that a defective plug connection to the fuel pump was causing the issues. After fixing the connection, the car's performance returned to normal.

Hey, that sounds familiar. I had similar issues with my old Renault Megane. Engine stalling and the check engine light were the main problems. Have you checked the cable and plug connections to the fuel pump? Sometimes a loose or corroded connection can cause these symptoms. It's an easy thing to check before you start replacing parts.

Thanks! I haven't checked the cable and plug connections yet. Where exactly should I be looking for those? Is it something easily accessible, or will I need to take a bunch of stuff apart?

On my Megane, the fuel pump was under the rear seats, but I'm not sure about your DS4. You might need to check your car's manual. It's usually not too difficult to access, but you might need some basic tools to remove some panels. If you're not comfortable doing it yourself, it might be worth taking it to a workshop. They'll be able to diagnose it properly.

You were spot on! Took it to a mechanic, and it turned out to be a defective plug connection to the fuel pump, like you said. They fixed it for 95€. Runs like a charm again. Thanks for the help!
