VCX CXDiag Allscanner J2534 Interface What you Need To Know

Hi, you bought all software activated, I have for BMW only (so-called DOTNET for one car), works pretty fine with E-Sys, ISTA, NCSExpert, but a year of cars starts from 2004 and up, if older cars, it doesn't work, has to use ICOM. Planning to buy for MB, but of course better to use the original MB SD C4 if it's possible. Make some videos with AUDI/VW, JLR, just interesting how it works for these cars :) Thanks for sharing useful car repair info :)
