My diff. took about 1.2 qts, much more than a 1/2 Liter, and $43 for a Liter of oem gear oil is 4 times the cost of RedLine, and many would consider RedLine to be superior than the OEM. The BMW TIS has it as 1 and 1.2 Liters for non-M E90 diffs.
From Mike Miller's old school maintenance schedule:

I use and also recommend Red Line 75W-90 synthetic gear oil, drain interval 30,000 miles in any BMW differential except as noted below [M diffs]. It is okay to use Red Line 75W-90 in place of BMW “lifetime fill” gear oil.
