XC70 Sporadic Errors

I'm having trouble with my 2012 Volvo XC70 gasoline engine. I'm getting sporadic errors while driving, intermittent error lights, and system failures, mostly audio/navigation. Sometimes control units shut down or become unresponsive. The error memory has a stored error. Has anyone seen this?

Sounds familiar. I have an XC70, and I was experiencing something similar not too long ago. Did your scan tool point to any particular system or control unit?

The scan tool indicates a possible defective cable connection of the control unit, specifically related to the BUS system. Does this sound like what you experienced?

Yes, that sounds exactly like the issue I had. I ended up taking it to a workshop, and they confirmed the same diagnosis. They replaced the defective cable connection, and the problem disappeared.

Understood. Thank you for the information. I will proceed to take it to a workshop as well. I was hoping to fix it on my own but I don't want to make things worse.
