Problem:
I got the vxdiag vcx se BMW firmware and license updated, but still cannot communicate with vehicle. Software version ISTA+ 4.46.21. Any solution?
Possible solutions from vxdiagshop.com:
ISTA 4.46 requires latest BMW driver.
VXDIAG Update BMW Driver for ISTA-D 4.46 and Adds Analysis Diagnostic Mode
Update BMW ICOM driver in VX Manager.
Then update firmware and license.
If still not communicate, reinstalling BMW driver will fix the problem.
