What's this rubber part? rear transverse link (outer ball join)

Is the boot on the outer ball joint of the transverse link actually
fractured or, as it appears in your picture, just deformed?  If the latter,
just relube both the inner and outer ball joints by injecting lube (I use
GL-5 gear oil) with a hypo needle thru the boot.  This deformation was most
likely caused by your dumb wrench who tightened the retaining bolt with the
suspension at full rebound, rather than at static ride height.

If the boot is fractured, the Audi fix is a new transverse link.  Very
expensive!  But there are lots of these parts in the AWs, any 44 chassis
car.  If you wish to replace just the outer ball joint, remember that the
two joints are keyed together within the camber adusting coupling nut, thus
must be removed together.
