ALZ? limited-slip?

What the heck is ALZ???

It sounds, based on your description, that this ALZ critter is actually a 100%
locking diff that locks automatically based on detection of spin, I am guessing
though. If this is so, Audi marketing nomenclature not withstanding, I would not
technically characterize it as a 'limited-slip' diff.  would call it automatic 100%
mechanical locking - it is either 100% locked -or- it is open - there is no 'limited-slip'
in the traditional way the term has been used historically.
