I'm reading my owners manual. It says drifting in neutral w/ engine off will damage the auto trans.

well the idea is that you gain inertia and let it roll minus engine
braking effect you save some gas
Now I do this all the time driving stick (N. Frontier CC 6MT)....
examples:
rolling to a Stop sign/light
rolling in traffic
rolling down hill
going in N to stay within speed limit after acceleration
you get the idea
just use inertia as needed...I thought same applies to the tip but I guess I was wrong

Has more to do with lack of lubrication at the tailshaft.
With the engine at idle or turned off, as autosolutions indicated, the transmission oil pump is turning slow or off as well. This means that excess oil spray inside the transmission, which would normally be lubricating many parts inside the transmission, isn't there. These parts include several bushings at the extremities of the transmission, such as the tailshaft bushing.
Coasting slowly over a short distance (a mile or two) isn't really a big deal, because there's usually enough leftover lube at the bushings. But over long periods of time, or at a fast enough speed, this could cause the bushings to seize or gall, taking out the parts they're supporting as well. There's a lot of factors involved, but suffice it to say it's not something you want to do all the time.
Doing this in a manual transmission may or may not be as bad, depending on whether or not the countershaft(s) are spinning. The countershafts are what throw the oil around in a manual transmission, and coasting with the engine turned off may drive the countershafts, or it may not, depending on the design of the transmission. I haven't been inside an Audi six-speed, so I can't tell you.
