XC90 BUS System Errors

I had similar issues with my XC90. Random system failures, audio cutting out, that sort of thing. Have you checked the cable connections to the control units? That was the culprit in my case.

Which control unit cable specifically? And what was the error code you pulled?

I didn't pull the error myself, unfortunately. The workshop identified a defective cable connection to the BUS system. I'd recommend getting it checked professionally, as diagnosing BUS issues can be tricky.

Thanks for the insight. Checked the BUS cables and found a loose connection. Cleaned and re-seated it. Seems stable now. Repair cost: 155€ Appreciate the help.
