Make sure you can undo the filler plug before you undo the drain.
Buy your oil in squeezy bottles with a plastic tube attached, and squeeze the oil in untill it reaches the level of the filler plug.
Car should be level of course.

Just noticed from your OP that the diff's not on the car.
Suppose you could get away with draining the old oil out of the filler plug. Set the diff level to fill.

both holes are on the back,lower to drain, fill through the top hole until the oil starts dripping out, non lsd has holes in line , lsd has holes offset,im led to believe.

No, not true, the casings are the same between both types, it's the internals that are different.

Oil capacities are the same also bewteen open and LSD.

0.9 litre for 316i - 320i and 324d
1.7 litre for 325i and 324td

Not really slightly less, only just over half.

Unless it's an LSD, in which case you need some Castrol SAF-XJ
