Someone mentioned that after upgrade/downgrade there might be an error occuring in the car computer, something I should worry about? Or is it something that just is registered in the car computer and all but radio works same?
Also, the SD card should be FAT or NTFS formatted?
And what did you mean by "poor lead"? Sorry, I'm Polish and trying to figure out what "lead" are you talking about?
Stick to Fat32. Other posters have reverted to 515 from 516.
SVM (serial version management) error is a flag that is picked up on a VCDS /
Obdeleven scan. They don't effect how the unit works. Just a flag to say the software has been changed. They can't be cleared using the normal clear button that you press in
Obdeleven. A decode, code has to be computed. There are websites that do that for you these days.
I went into it in this post:

You can compute the clear code via convoluted methods or use a newer website that does the Hex stuff for you, still need to use a
coding tool to feed it in thou:
fix DTC 1555 / B201A (Checking software version management)
mib-helper.com
Basically its a little trap that Vag sets but the decode algorithm was discovered. For the mib2 standard you can do that. For the mib2 high you can do that as well but the Mib Tool for the mib2 high has it's own built in clear function so you sit back and let it do it, itself. Mine have all gone now with my high unit. Previously I used the method posted up.
A lot of people drive about with SVM errors not knowing. Only if a perfectionist that you get rid of them.
Btw you can only upgrade / downgrade within a series release, not across. YXX would be a release for mib2 standard. Y is the series (train). 515 is a 5 train. You cant easily move between trains, that why on the thread of recent people have been told to keep within series for home updating. Will brick the unit if you jump series. Some technical posts on here that cover it but requires programming.
Also, I tried downgrading 0516 -> 0515, but it won't let me "Start", it's greyed out. It sees the firmware on the SD card and all, but doesn't allow to click start and next to the different components I see either N/A (once or twice), N (quite few) or D (also quite few), I guess N/A means nothing for my system, N means nothing changed in the firmware and D means Downgrade? but I dunno
how to push the downgrade to install
How to start your downgrade off, I'll let someone else reply. Suspect you need the SWDL menu by unlocking the developers menu. The backend menu. The front menu is for simple upgrading. That's the post above the one in the link I did on the
Ateca thread on
Obdeleven.

. That D will change after its done it.
