Does it matter if I use E-Sys 3.18.4 v47.5 versus E-Sys 3.22.5? Do I need PSdZdata 49.1 (which I understand likely doesn't work with 3.18.4).
I realize E-Sys 3.22.5 will (likely?) require the purchase of a token (perhaps the former does, too? I'm still downloading and am unclear on that because I haven't gone through the setup process). Obviously if paying for the token is part of this process then... so be it.  But I just saw no reference to that anywhere in this long thread, so... again, maybe I'm asking a question publicly that shouldn't be asked. Mea culpa? Help? 
[Edit: I did just have the vehicle in for service yesterday due where they did a CAS software update for recall B61 38 12 if that matters] |
Yes, it matters.
The PSdZData version you use to code the car must be >= than the last version of ISTA/P used to program the car. The application of SIB 61 38 12 most certainly had the dealer reprogram your car with current ISTA/P, which will be either 2.49.1, or 2.49.2 depending on if they updated their ISIS server in the last few days.
The last version of PSdZData working with E-Sys 3.18.4 and "Free" EST Token for F25 Chassis is 48.3, which you will not be able to use.
You will need 49.x PSdZData, which in turns necessitates newer E-Sys with Token.
