Seat Cordoba diesel engine running rich
Summary of the thread
The 2001 Seat Cordoba diesel engine is experiencing issues such as reduced power, rough running, higher fuel consumption, and jerking during acceleration, with the check engine light on. The suspected cause is a defective injection valve or injector. Suggestions include checking the air filter and oxygen sensor, as these can affect the air-fuel ratio. Ultimately, a professional inspection confirmed a faulty injector, which was replaced to resolve the problem.

Yes, the jerking was definitely there, and the check engine light was constantly on. I replaced the oxygen sensor myself, but that didn't fully solve the problem. Eventually, I had to take it to a workshop. They confirmed a faulty injector was causing the rich mixture. Given your symptoms, especially with it being a diesel, it's likely a similar issue. I would recommend getting the injectors checked professionally.

Interesting. You mentioned the oxygen sensor. Did you experience jerking during acceleration as well? And did your check engine light come on? I'm trying to narrow down if it's the same issue. My air filter is relatively new.

Took it to the workshop. It was indeed a faulty injector valve. Replaced all four for 515€. Runs like new now. Thanks for your help!

I had a similar issue with my Cordoba, although I drive a petrol version. Reduced power, rough running, the works. Have you checked the basics like your air filter? A clogged filter can mess with the air-fuel ratio. Also, consider the oxygen sensor; a faulty one can cause the engine to run rich. It's worth a look before diving into more complex things.
