It's generally normal. With AWD doing a slow turn at full lock is an extreme condition and can cause some of the wheels to skip and grind due to the differentials binding. The newer diffs are less prone to this. For example, I don't get it anymore on my RS5, but I had it on my previous B7 S4. Is yours a 6MT? The 6MT has the old torsen diff, which is more prone to this than the new crown-gear center diff that was introduced with the RS5 and later fitted to the B8.5 S4/5 S-tronic.

Hard to tell w/o driving it if what you experience is normal. I really haven't noticed this phenomenon since I sold my B7 S4 over 4 years ago and I've driven many different Audi models since then besides my RS5. You may wanna see if you can find a used S4 on a dealer lot that you can test drive and compare it to yours.

It is normal. What you are feeling is the tires scuffing the road surface because the turning radii of the inner and outer wheels is different and at slow speed and the quattro system cannot compensate for the difference. BTW, the same thing occurs with my AWD Mountaineer. This is a very common concern with new Audi owners with Quattro.

That'll happen
yep. the slower the speed, the more steering angle you put in, the more of this shudder you'll end up getting. this is indeed normal for the reasons others have already listed here -- this activity taxes the differentials which creates some choppiness.
with the automatic transmission you don't have the clutch to help mitigate this effect, but I can't imagine it stalling your engine unless you're doing this in reverse up a steep hill. (in which case, you probably need to reconsider what you're attempting to begin with.)
it's just par for the course, but a very reasonable question. hope you're enjoying your car!
