Mercedes MB SD C4 Plus Connect Compact 4. I have several problems.
Although I already bought a Windows 10 key to run the system.
I start the Config Assist and try to read out the hardware ID as prescribed.
It doesn’t find anything and runs for hours with no result.
How to fix?
Uninstall all hidden virtual drivers. I Had the same problem.
We connected a newer car to diag and xentry always shows Data is incorrect. Older cars works well, because it opens in DAS.
Hope it helps!
