Apps like VagDPF and Torque utilize the universally available diagnostic data and arrange it in a user-friendly display. Even if your car is "not supported" there will be usefulness because it uses data that is required to be made available for use by "code scanners" so to speak in all cars since 1996. That's the simplest way I can think to dumb it down and type it quickly for a quick off the cuff forum post for general consumption. IOW the data is there and the apps use it and have it available and you can see it, even if the "specific" car is not explicitly listed as "supported". just have to think a "little" outside the box is all.
The car selection in vagdpf only selects different combinations of these universally available parameters to display. For example, some cars do not have LP EGR, but you may or may not care about that anyway. it's not a hard and fast "My car won't work if I don't see it in the list" kind of thing. It's simply a matter of selecting the combination of things you want to see displayed.
For the VagDPF app, just choose the option to let the app choose your car or automatic parameters selection or the similar option. (don't have it in front of me and can't remember the exact words used for the options, just look for "something like that") Or else scroll through the different cars, trying each in turn, until you find a combination of displayed parameters that you like, simple as that.
