Seat Leon diesel engine issue

Sounds familiar. I had a similar issue with my Leon. Check the fuel quality and maybe replace the fuel filter. When the wrong fuel gets into the combustion chamber, it messes everything up.

Thanks for the quick response! When you say 'similar issue,' do you mean the engine stalled at idle and the check engine light was on too? Did you also have an error stored in the error memory? And what exactly do you mean with fuel quality, as I always take the standard diesel at the gas station.

Yes, same symptoms. Check engine light, stalling. The error memory also had a message about the fuel mixture. By fuel quality I mean if somehow wrong fuel ended up in the tank. I would recommend going to a workshop to check the cable or plug connection of the component if you can't find anything visibly wrong yourself. They should be able to diagnose it quickly.

Thank you so much! That's exactly the information I needed. I took it to the workshop, and they found a defective plug connection. They replaced it, and the car is running perfectly again. The repair cost was 95€. Appreciate the help!
