Seat Alhambra Diesel Engine Running Rich

I'm experiencing a problem with my 2013 Seat Alhambra diesel, which has 97815 km. The engine seems to be running too rich. I've noticed a significant reduction in engine power, and the check engine light is illuminated. Furthermore, the engine runs rough, and fuel consumption has increased. There's also some jerking when accelerating. Could a defective injection valve or injector be the cause? I already checked the spark plugs but they seem alright.

The 2013 Seat Alhambra diesel engine was running rich, leading to reduced power, rough running, increased fuel consumption, and jerking during acceleration. The initial suspicion was a defective injection valve or injector, despite the spark plugs being in good condition. After further investigation, it was confirmed that a defective fuel injector was the cause, and replacing all four injectors resolved the issue, restoring smooth engine performance.

Did this summary help you solve your problem?

Sounds like a rich mixture issue. Does it have any trouble starting? Have you ever cleaned the intake manifold?

Starting is a bit harder than before, yes. And no, I have never cleaned the intake manifold. Could that really cause this kind of problem, and would that also affect the catalytic converter and oxygen sensor?

Hard starting points to the same thing. Cleaning the intake might help a bit, but if it's a bad injector, it's a bad injector. Save yourself the headache, get it checked by a workshop.

Turns out it was a defective fuel injector. Replaced all four, and the engine is running smoothly now. The cost was 515€. Thanks for the input.
