VIN not recognized so off to a bad start.

Specifying manual selection works for Sprinter 907. 

Problem 1: Reading VIN will fail for any 907.x model selection.

Diagnostic system will initialize and list modules. Auto scan will work showing various modules with Pass and a couple with fault codes. 

Problem 2: Attempting to Quick erase or attempt to manually select any module and I receive the Device unable to communicate with the control unit. I have tried with both bluetooth and usb cable. Same problem for any module I select. 

Problem 3: Sometimes with auto scanning, software will crash and restart back to vehicle make selection.
