Mercedes C3 Multiplexer Mercedes benz 12/2015 Xentry Initialization of the multiplexer has failed Problem:

I have DELL D630 with Xentry 12/2015 and MB Star C3 multiplexer from obd2tuner.com. I have connected many cars (W202, W203, W210, W211, W245, etc) and there is no problem with connection – everything is working like a charm. Some days ago, I have bought W204 C280 from 2007. After I choose model, engine and transmission, and I go to diagnostic I see this:

“The diagnosis application is being started…”

and few seconds later this:

“Initialization of the multiplexer has failed”

My Mux is not compatible with W204? I searched few hours without success.
