Seat Exeo electrical malfunction and navigation failure

My Seat Exeo, build year , with a Gasoline engine is giving me grief. Mileage is at km. I've got an error stored in the error memory, plus what seems like a general electrical malfunction. The navigation system is completely dead. A preliminary check suggests implausible programming of the control unit. Could this be vehicle software related?

Sounds like ECU problems. I had a similar issue with my Seat Leon; the onboard diagnostics kept throwing up errors. Have you checked for any software revisions?

Software revisions for the ECU? I've only ever refreshed the maps on the navigation. Is this something I can do myself, or is it workshop territory?

Best bet is to take it to a workshop. They can perform a proper software refresh. In my case, a simple refresh fixed the control module issue, but it requires specific tools and software.

Took it to a trusted workshop, and they confirmed the ECU programming issue. A software refresh, as suggested, resolved the error, and the navigation is working again. Total cost was 240€. Thanks for the insight.
