Parm and Dado have pretty much covered the common weaknesses of E39s but I see that you have a 6 speed. The clutch is reputed to be weak on the 540s but the 6 speed tranny is quite strong, the only thing that I recall about the manual tranny is that the bushings in the shift mechanism may expand and make the tranny hard to shift, I'm not sure how often or easy/expensive this is to fix.

... oh yeah you should check the valve covers and valley pan gasket for leaks... happens on all 540s.
