I got Benz VCI C6, after PC Crash Xentry wis/asra and epc are Not Running. I contact at the dealer for remote assistance.
Finally! I got reply:
The xentry software is activated, the driver is also installed, you connect the car to test.
At first, I thought the car is no connected yet. The dealer found the voltage is only 1.29v. That is not the car but a power supply in my office, that was the USB Power.
WIS/ASRA and EPC are running too, I can test it on a car
Thanks to their remote assistance from obdexpress.co.uk , the engineer is my hero.
For your information, I also have MB SD C4, whenever I encounter problem, I contact them for remote assistance, and they manage to help solve them, they do a great job.
