I have the same engine as you except we use 1 liter bottles, I put in six bottles, checked the oil level which takes forever, and it was down .5, added half a bottle and it read full.
6.5 liters = 6.87 quarts
6 liters = 6.34 quarts
.5 liter = .53 quart
Agreed, if anyone in BMW's engine design department reads these threads please bring the dipstick back or add it to the options list.
