Seat Cordoba Diesel Smoke and Warning Light
Summary of the thread
A 2005 Seat Cordoba diesel was experiencing a warning light and smoke during acceleration, with the Diesel Particulate Filter (DPF) failing to regenerate. The suspected cause was a faulty exhaust back pressure sensor, which can indeed prevent DPF regeneration and lead to emission issues. After replacing the sensor, the warning light turned off, and the smoke issue was resolved, confirming the sensor as the problem.

When you had the issue, did you also have the DPF regeneration problem? Where is the sensor located exactly? Is it easy to check?

Yes, I also had the DPF regeneration issue. I didn't check the sensor myself; I took it to a workshop. They said it was causing the problem. It is probably best to get it checked professionally to be certain.

Right on the money. It was the exhaust back pressure sensor. Replacement cost 245€. The warning light is off, and the smoke is gone. Thanks for the help.

Sounds familiar. I had a similar issue with my Cordoba. Was the smoke black? Could be the exhaust sensor. Have you checked the sensor?
