I thought updates make things better Not worse now I have to Manually enter the VIN #

  • Will this scanner reset the clutch statistics on an Aston Martin vantage magneti marelli ASM (after clutch replacement). I have the NT530 and it doesn’t have that facility.

  • Bi-directional control, component tests or actuation is a very important function of a diagnostic tool. I don’t see that mentioned in this review. Why not or did I overlook it? I have an NT630 which does perform tbi-directional tests but am buying a scanner which works on more than 5 manufacturers, the NT644 is one I considered but without all the info I won’t buy it.
