Nope, BTDT.  I don't know about the newer Audis, but I found that
Locktite would hold the driveshaft nut on one side only.  The
other side came loose within miles (I forget which side was what).

It will depend on how far the nut is deformed from it's locking
shape that determines if it will hold.  It is much safer to replace
it anytime it is removed.
