Seat Tarraco Hybrid Issues

I'm experiencing some strange issues with my 2021 Seat Tarraco Hybrid. It has around 120360 km on the clock. I'm getting sporadic errors, and sometimes the audio/navigation just dies. I've also had temporary shutdowns of control units. OBD-II shows an error stored in the error memory. Anyone else had this?

A 2021 Seat Tarraco Hybrid with 120,360 km is experiencing sporadic errors, including audio/navigation failures and temporary shutdowns of control units. The issue is traced to a defective cable connection to the BUS system. The problem was resolved by repairing the cable connection, which cleared the error messages and restored functionality.

I think I had something similar with my Tarraco. The audio kept cutting out, and sometimes the display would freeze. Did you get any warning signal lights?

Yes, I did get sporadic errors in driving mode or sporadically illuminated error lamps. Did yours also affect other systems, or just the audio?

Yeah, that sounds familiar. It's probably the same thing then. Mine was a defective cable connection of the control unit, the connection to the BUS system. I'd suggest taking it to a workshop; they should be able to diagnose it quickly.

Thanks for the input. Turns out it was a defective cable connection to the BUS system. Engine diagnostics pointed to it. Service required message is gone now, and the audio/navigation are working again. Cost me 155€ to get it sorted.
