DS5 Combustion Misfires

Alright Citroen gurus, I'm tearing my hair out! My 2012 DS5 hybrid is throwing combustion misfires like confetti. 197262 km on the clock. Engine's running rough, check engine light's on, jerks like crazy when I try to accelerate, and power is way down. Suspect a dodgy injector, but where do I even start?

I had a similar issue with my DS5, although I can't say for sure if it's the exact same. Rough running, check engine light, and hesitation on acceleration. Have you checked the fuel pump relay or any of the ignition coils? I'm not an expert, but those were things mentioned when I was troubleshooting my car.

Interesting! Thanks for the input. Ignition coils, eh? I was so fixated on the fuel injection. Did yours throw any specific codes? And how did you eventually nail down the culprit?

Yes, the error code also pointed to combustion misfires, which led me down a rabbit hole. After checking a few things myself, I ended up taking it to a workshop. They diagnosed it properly. I'd suggest getting it professionally diagnosed; it could save you a lot of time and potentially money.

Cheers, I appreciate the advice! Bit the bullet and took it to a mechanic. Turns out it WAS a faulty injector! 515€ later, she's running like a dream. Thanks for steering me in the right direction!
