Laguna Diesel Fuel Issue

I'm having some serious issues with my 2010 Renault Laguna diesel. It feels like it's not getting enough fuel – the engine power is way down, the check engine light is on, and it runs super rough, especially when accelerating. It's got 181611 km on the clock. Could this be a catalytic converter problem or maybe the oxygen sensor? I've also read something about the intake manifold and the mass air flow sensor, but I don't know. Any ideas what could be wrong?

I had similar symptoms on my Laguna. Could be the fuel injectors.

Really? What happened with yours? Was it expensive to fix? What mileage were you at?

Yes, it was the fuel injectors. Just get it to the workshop. It's probably that.

Thanks for the tip! It was indeed the injectors – cost me 515€ to replace them, but she's running like new again!
