Problem:
Tested VXDIAG VCX SE Benz and 2025.03 Xentry software on a 2001 Mercedes W203 270cdi. It only scans a few control units, no all.
Solution:
VXDIAG does not work very well on older K-line Mercedes models pre-2005. Same as openport with xentry.
It is common if it only scans a few control units on these older models.
