This has been an interesting read!
I use the Jaltest (by Cojali) Off Highway software, and I really like it! It is not "Dealer Software" but for a fellow that does ANYTHING it is priceless!
Forced Regens, DPF Resets, EGR Resets, Codes, Live Data, Injector Code Programming, all sorts of things. I did have a few machines that I could not do what I wanted to, but a phone call, and a Teamviewer session, and they had me doing what I wanted!
It is a yearly subscription-based, but they push out 3 Updates per year, and I found it worth the fee!!
This has been my experience so far! My opinion is subject to change without notice.
