I don’t want to keep the car more than one year but still I will change all of them. Seems there is more than 2mm wear, tires are Bridgestone 225/55 r18 102v winter ones.

Wow, that's close.
If you drive the car like a little old lady and only to church on Sundays, I'm not so sure you should bother with the other 3. However,
if you drive the car hard (or sporty), you'd be better off in the long run to change them all.
Another way to look at this...if you don't replace them, you'll always be worrying about it. If you do, you'll forget about it in a few
short weeks or so. It might be well worth the $1,000 or whatever it is, to just get it over with.
A6 manual says that thread wear is no issue, but they must all be identical models.
Mine doesn't say that. Perhaps what you are reading applies to 2WD vehicles.
This is in my 2023 A6 owner manual: "Applies to: vehicles with all wheel
drive: All four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam
aged by different wheel speeds.
For this reason, in case of emer
gency, only use a spare tire* that
is the same circumference as the
regular tires."
Although this doesn't specifically mention treadwear differences on the regular tires, it does
imply that using tires with different circumferences can damage the drive system. Since significant treadwear differences
would effect the circumferences of the tires, this pretty much backs up what most of us have been saying.
It's unfortunate the manual doesn't more specifically address the issue.

Yeah, but that implies that you should not use a smaller size spare wheel, not a 3-5mm difference in thread wear. If it was relevant they would have said it explicitly, they are German after all.
