Per the Bentley BMW 3 Series Service Manual, Page 333-1:

Rear differential capacity non-turbo: 1.0 ltr (1.05 qt)

Rear differential capacity turbo: 1.2 ltr (1.3 qt)


Per the Bentley BMW 3 Series Service Manual, Page 333-2:

Tightening Torque (all) Fill / Drain Plug: 44 ft-lb

So, a 328i (like mine) will take one US quart, unless you flush & clean all the old fluid from the inside by removing the dif housing cover first! Red Line polyo ester (PE), Group V base stock synthetics everywhere is the way to go!!
