Seat Inca Diesel Mixture Preparation Error

I'm at my wit's end with my 2002 Seat Inca diesel. I'm getting a 'mixture preparation error,' and it's driving me nuts! The check engine light is on, the engine's running rough, there's reduced power, and it jerks like crazy when I accelerate. Sometimes, it even stalls at idle. Could a faulty injection valve be the culprit? I am trying to avoid checking the catalytic converter, if possible.

Sounds like the same issue I had with my Inca diesel. Rough idling, power loss, the whole shebang. Did you check the injectors? It felt like driving a tractor when mine went bad. Like trying to run a marathon with a blocked nose, gasping for air, you know?

Injectors, eh? I've cleaned the throttle body and checked the mass airflow sensor, but the problem is still there. I haven't touched the injectors yet. How did you confirm it was the injectors specifically? Did you notice any other symptoms besides the ones I mentioned? I would be checking the spark plugs and oxygen sensor too, but it is diesel...

Yep, sounds exactly like what I experienced. The symptoms you described are spot on. I didn't have the equipment to test the injectors properly myself, so I took it to a workshop. They did a proper diagnostic and confirmed it was the injectors. Honestly, save yourself the headache and get them professionally checked. It could be something else, but those symptoms strongly point to injector issues. Plus, messing with fuel injection can be tricky. Not something you want to experiment with.

You were spot on! The workshop confirmed a defective injector after diagnostics. I had all four replaced for 515€ including labor, and now the van is running smoother than ever. No more jerking or stalling! I really appreciate your help!
