Recently some VXDIAG VCX DoIP users reported that they got problems during online programming with the Pathfinder software. It keeps downloading vbf file, sometimes it disconnects and can’t not detect VCI which lead to the failure of the programming process.
Here is the working solution from vxdiagshop.com:
Download VXDIAG JLR DoIP Pathfinder VCI patch
VCI Software (JLR)-126.96.36.199.exe
The problem will be solved.
