Skoda Fabia MOST Bus Fault

I have a Skoda Fabia, build year 2019, with a gasoline engine and approximately 220392 km on the odometer. I am experiencing a MOST bus fault that is preventing the audio output from working. This has rendered the audio system and navigation system useless. Error memory confirms the MOST bus issue, suggesting a defect within a control unit on the bus. Has anyone encountered similar problems with the automotive protocol within the bus network?

I had a similar issue with my Skoda Fabia. Did you check the control units connected to the bus network? In my case, the issue was with the navigation system causing the entire data transmission to fail.

Interesting. Could you elaborate on which control units were affected or how you diagnosed the navigation system as the source of the bus system problem?

Yes, the navigation system was the problem. The workshop confirmed it. They said the unit was sending corrupted data across the bus, disrupting the entire audio system. I would advise having a professional diagnose each control unit on the MOST bus to pinpoint the defective component.

Thank you for confirming my suspicion. The MOST bus fault was indeed the culprit. The audio system now works again. Repair cost was roughly 1000€. I hope this assists others facing a similar predicament.
