Problem:
ITSA+ 4.48.1 software did not communicate with VXDIAG VCX SE BMW scanner. Status reserved. Update firmware and license, reinstall driver, all the same problem.
Solution:
VXDIAG BMW driver is not ready for ISTA+ 4.48.1 yet.
VXDIAG engineers are working on new version ISTA and will publish new version driver soon.
