2006 A4 B7 Rear Differential Fluid Change
 

Hello, can somebody please post a link on how to (preferably with pics) change the fluid. Some forum says to use a 10mm hex bit to remove/reinstall the fill and drain plugs. I can’t see a 10mm hex plugs but seen plugs on left and right side of the differential that can be removed by a T55 torx. I’m not sure whether these are the plugs and need correct DIY procedure. Thanks in advance!
