IHU to VGM connectivity problem - glennda5id - 05-04-2026
2021 XC40 BEV software 5.0.5 update a few weeks prior to this issue starting.
IHU has no internet connectivity but SOS light is white and Volvo Cars app works.
I see VGM-U105E00 error code occasioanlly.
Orbit cannot write config changes because it cant talk to the IHU, I assume communication is via VGM?
Everything else in the car works fine.
Any thoughts?
