Peugeot 3008 mixture preparation error

Alright Peugeot gurus, I'm pulling my hair out! My 2009 Peugeot 3008 diesel is throwing a 'mixture preparation error'. It's got 102037 km on the clock. The check engine light is on, power is way down, the engine runs rough, jerks when I accelerate, and sometimes even stalls at idle. Could it be the oxygen sensor or a rich mixture? I'm lost!

Whoa, sounds rough! I had something similar with my 3008. Have you checked the mass airflow sensor or the intake manifold? Could be a vacuum leak somewhere messing things up.

Interesting! Mass airflow sensor or intake manifold, huh? What kind of symptoms did you have exactly, and what ended up being the problem?

Yeah, the check engine light was on, and it felt like the car was struggling to breathe, especially when accelerating. Never stalled completely though. I ended up taking it to a workshop, and they sorted it out pretty quick. Might be worth doing the same!

Okay, that's super helpful! Thanks for the insight. I'll take it to a shop and mention the mass airflow sensor and intake manifold. Just got it back! Turns out it was a defective injector valve. Cost me 515€ to fix, but it's running like new again!
