can someone help me? i have installed xentry passthru as described, and it works good, but i am trying to connect to a w220 2000 s class, so xentry changes over to DAS. the tool i am using is a VCX nano 5054 for VW. the tool connects to the car reads the VIN and voltage, when i try to access a module i keep getting.

" initialization of diagnosis multiplexer failed. possible cause :{ diagnostic system data sectors are incompatible or faulty. please contact the user help desk."

i have reset computer and retested. tried various drivers but will not go any further.  

the tool is connected via a wifi hotspot, and i do notice the voltage drops out every so often and returns. but do you think that tool is the issue or a software fault?

VCX nano must always use latest firmware & driver j2534?, have you updated firmware & driver & have Vxmanager installed ?, and try connect with the VCX cable, also disable or remove antivirus - it interferes with VCX nano

firmware updates did solve some issues for me

I will check for latest firmware on device, i am nearly sure is is up to date. and vxmanager is installed.

i am unsure how to update the driver, can you advise of the process?

Im not sure if this makes a difference but i run xentry though a VM running win7. on this machine i also have VW ODIS and JLR SDD, ODIS works 100% and SDD untested.

i cant use a cable as the middle of the USB is missing and the seller is AWOL(long story) but can successful access it via ip and and a mobile hotspot, i am currently trying to find someone local who can carry out the repair to the USB.

but essentially should the VCX nano support this application?
silly question but when you launch xentry do you use the VXDIAG J2534 driver?

thanks for your help, it seems there is not a hell of a lot of information about VCX nano to reference
