I'm troubleshooting an issue(s) with my wife's 2016 XC90 T6. Or, at least I'd like to be troubleshooting better than I am.
I've only sporadically been able to connect with OrBit (never with VDash) to get any information from the car. When it does connect, the connection quality ranges from Red at less than half on the little indicator bar, to Orange at about 2/3 up. I've never seen a green connection with OrBit.
Almost always, I get "VOE connection is present but the car is not responding". When I run a WireShark trace on my VOE adapter's Ethernet port, it indeed shows "50 Vehicle identification request" but no response from the car. In fact, I see a large number of packets from 169.254.158.215 (my laptop's IP) to the car but not a single one from the car to my laptop.
I don't want to pay for a VIDA subscription until I can reliably connect with either OrBit or Vdash... $100 on a failed experiment is a bit steep.
My understanding of how these units fail is that they just die. No connection at all, just a dead socket. This seems to be something different since I can, very rarely, get a (poor) connection.
A battery reset is my best chance at connecting... in all prior instances where I've been able to connect, I've previously done a complete shut down and disconnect of my laptop, then performed a battery reset (disconnect the negative battery terminal for a few minutes). A suggestion on the OrBit FAQ suggests pulling the backup battery for the VCM, to do a true power-down. I did that and left it disconnected.
That allowed me to connect once, but not since. (I have the "Volvo OnCall Service Required" message now, which makes sense.)
Anyway, before I drop $700+ on a replacement VCM, I'd like some reassurance this is actually a failing unit, not just noise in another system.
Thanks for any help you can lend!
