XSeries-forum

Hi all just serviced my car all good but how on earth do you change the front diff oil  :blink:
Is my front diff part of the sump as I have a metal  plate  covering the sump and to take that of you have to undo the antiroll ball
Is thus right or am I missing  something

Nope that sounds about right!  These cars have lots of shields (aerodynamic improvers) underneath - the X6 is even worse! - and it is part of the 'don't let Owners service their own cars' approach by BMW (and many other manufacturers) so they make even more money out of us.... >:(

You have to take off the plastic tray, and the metal reinforcement plate- the bolts for the reinforcement plate are not re-useable- you need new ones from BMW - they are £70 odd quid, if you message Cotswold BMW on the forum you get a bit of discount, lots of people do re-use them but they are stretch bolts and you're not supposed to - your choice!

I've reused mine, as had that plate off about 10 times.... too expensive to be buy new every time lol, but when all work done, she'll get new ones  ::)

Ok thanks for your help and advice
