Hi Jim,
Apolgoies for the late reply, I've been away.
The dongle lights up
We purchased 5 dongles all at the same time when we bought VW 2015, they all work fine.
All machines are Windows 10 (creator edition)
We used to be able to swap dongles between machines, now this doesn't work - I have tried removing everything and resinstalling and this doesn't solve the problem
Thanks
Carl
