Hi all
Did search for this but nothing too much info came up
I'm going to change the diff oil in the 316i- but I'm sure I've seen negatives about changing the oil if its been in there a while- eg will do more harm than good:
Views please?
If its necessary (which I'm sure it is to replace as I cant say for sure when it was last done) and the diff is getting a little noisy, whats the best fluid to put in?
TIA

Changing Diff Oil

Top tip: Undo the upper filler plug BEFORE you drain the old oil out of the bottom plug.
Draining the diff then finding you can't get the new oil in is a tad inconvenient.

These are sensations as hard to forget as they are to ignore.....

The oilman (on here) recommended Castrol Differntial SAF-XJ. BMW slipper diffs are referenced on the notes on the back of the bottle.

Oil capacity is 0.9L and yeah its a good thing to change the oil, that rear diff gets noisy.!
I did mine and its now very quiet. Just try not to get the oil on your drive way or skin, it stinks and stays there for a good while.

+1 for the advice to make sure the fill hole can be opened before you drain it.
Mine was so siezed I rounded the hex socket then smashed the case trying to knock it round using a screwdriver as a chisel. And that was with the diff off the car.
