XC70 Sporadic Errors
Summary of the thread
A 2012 Volvo XC70 is experiencing sporadic errors, including intermittent error lights and system failures, particularly in audio/navigation. The scan tool suggests a possible defective cable connection related to the BUS system. A similar issue was resolved by replacing the defective cable connection at a workshop, which is recommended as a solution.

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.

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?
