Here's exactly what I did.
- Disconnect the USB cable from the van. Turn the ignition off completely.
- Turn the key back on to power the van.
- Change the Privacy settings on your Head-Unit to the least secure.
- Do a full factory-reset of the head unit. Read the alerts as it sometimes says it hasn't done it properly. It took me 2 attempts.
- Reconnect to the VW WeConnect App on your phone; this needs your VIN number and connects to your van directly from VW.
