Is your car a C4? Don't they have some different fluid for the front drive shaft, which may explain those plugs on the passenger side? Dunno.

I did this job yesterday on my 993 and it's pretty much the same on every BMW and Porsche I've been underneath. Fill plug is on driver's side and you need to make sure you can get it out before you touch the drain plug, which, of course, is on the bottom. Mine used a 10mm hex on both bolts and I needed a breaker bar to get the fill plug out.
