VXDIAG Benz C6 2021.6 VCI Multiplexer Failed Solution

The problem goes like this:  I just try to read fault codes with Vxdiag Benz C6 new 6-2021 xentry version, but the VCI can’t make connection to car (W212).

Opens normally and start making connection, popup says VCI available But when starting diagnosis don’t connect, comes initialization of multiplexer failed fault info screen. See pic attached


VX Manager seems good, and I have update VCI and make reconnecting, nothing don’t help.

Autonumen.com working solution:

The problem can be solved by installing the new patch.

Download Xentry Patch 2021.06.exe within the VCI client here



I made that. Now it works. Thank you.
