car diagnostic tool

For you, which version of ISTA-D is the most stable, bug-free? 


For me: ISTA-D v.4.18.32
Latest for AGR rate change – Program bug free – short VIN …


4.15.16 for me,

later versions seems to be missing more and more functions

the latest version is ISTA-D 4.19.12


4.15 is momentan the best


4.15 the best.

It’s possible to use an older ISTA-D for example 4.15 with an newer DB 4.20
