hi guys,

I've searched high and low and cannot seem to get a straight answer...

I've got a '15 335d xdrive msport. It's coming up to 68k miles and although i do all my own servicing, I cannot see anything about diff or transfer case oil changes.

I've read they are 'lifetime' which is obviously BS. I have also read you cannot access the fluid in the diffs as there is no drain hole.

Does anybody know if a UK spec car like mine has:

Diff drain and fill holes?
Trnsf case drain and fill holes?
A requirement to replace the oils and fluids - i think yes, and perhaps i'm already a little late on that front!
Oil specs?

Sorry if this has been done to death elsewhere - if it has, I'll happily read more into it so send me over there!

Cheers
