I am experiencing a complete audio system failure in my 2003 Seat Cordoba diesel. The system is completely unresponsive; no sound, display blank. A diagnostic scan revealed an error stored in the memory, pointing towards a defective display. Could this also cause a Bluetooth problem, or speaker crackle that I heard before it failed? The estimated repair cost is 725€. I already checked dashboard controls, but I do not know where to start.

Seat Cordoba Audio System Failure

I had similar problems with my Cordoba's head unit. Is the static noise present regardless of the selected audio source? Have you checked the fuses related to the audio system? Sometimes a blown fuse can cause the entire system to fail.

The static noise appears regardless of the source. Where can I find the fuse allocation plan?

The fuse allocation plan is usually in the owner's manual or printed on a label inside the fuse box cover. Since the static noise persists across all sources, and given the error code, a defective display module seems highly probable. It may be best to have a workshop confirm the diagnosis before investing in a replacement.

The workshop confirmed the defective display. The audio system is now working after the replacement. The final cost was as predicted.
