Das use can as well I have xentry pt with vas5054/open port and I use it on my old slk from 2004 and is working ok.

then I have another question,
my old C4 has problem in kline, das not connect to car.
but UDS command through CAN is working in vediamo and DTS.
what do you think what kind of problem is it ?

Version of Xentry? UDS commands have nothing to do with the KWP protocol...

That is Xentry 2018 and 2021, C4.
Vehicle detection and DAS standalone was also working before.
someday later, xentry vehicle detect not work,
select car manually then diagnose in xentry still working for vehicle after 2007, vediamo all working,
but DAS standalsone cannot connect to car anymore.
