Ordered a vxdiag vcx nano 5054 Diaghead from you. Use odis 5.13 on windows 7.
From time to time, the diaghead does not recognize ignition correctly for few seconds and cuts out. I tested it on a Audi A3 year 2014
Tried a VAS6054 clone on the same machine and it works without issues.
I got the firmware updated and tested higher version odis 5.1.5. Still same problem.
The the problem is the actual/ last driver!!
I deleted VXmanager and then installed the version from your website again but did not install the latest update v220.127.116.116.
Now it runs stable and is not cutting out anymore.
However on the older release, it does not recognize ignition status (on/off).
I guess this is one of the changes you made with v18.104.22.1686.
The problem will be solved in the near feature.
Hope it helps.
