Laguna 1.9 dCi engine injector fault

While driving, when the rpm drops and it senses it's going to struggle, it immediately throws an injector error and cuts the throttle. No matter how much you press the gas, the rpm is high but the car doesn't respond to throttle. Does anyone know the cause of this? I had the injectors checked, they told me there's no problem. Do you think changing the diesel filter would fix it?

The biggest hassle you'll have with this engine is finding a mechanic. I had the dTi version, nobody wanted to touch it

I'd recommend starting simple - first the sensors, then the fuel filter, it could possibly be the wastegate
