Seat Cordoba Diesel Reduced Engine Power
Summary of the thread
A 2006 Seat Cordoba diesel was experiencing reduced engine power, with a fault code stored in the error memory. The issue was suspected to be related to fueling, but further investigation revealed it was due to a poorly executed chip tuning by a previous owner. The solution involved reflashing the ECU to remove the faulty tune, which resolved the power issue.

Dashboard light does illuminate intermittently. What was the cause of your similar issue? Was it also throwing a fault code?

Yes, it was indeed throwing a diagnostic code. In my case, the previous owner had installed a cheap chip tuning solution. Think of it like adding a performance part without ensuring the engine management system can handle it. The system detected inconsistencies, hence the errors. I advise getting a professional car diagnostic performed; it might be necessary to reflash the ECU.

Took it to a local garage with a good reputation. They ran a diagnostic and confirmed a fault code related to the ECU. A previous owner had chipped the car for more power, but it wasn't done well. They reflashed the ECU, got rid of the tune, and now it runs like new. Cost me 180€ Thanks for the heads up!

Reduced engine power and a stored error often point to sensor issues, but the fact that you mention a fault code makes me think it's something deeper. I had a similar problem with my Cordoba, though I can't recall the exact diagnostic code. Does the dashboard light illuminate?
