FWIW, BMW call it the A5S310Z. Filling procedure, torques etc are here: 



It is a two man job really - one with their foot firmly on the brake and shifting the gears. And the other doing the topping up. You need something to check the ATF temp - even if it is only a laser temp sensor pointed at the sump. And something to pump the ATF if it is low. If so, make sure the end of your pump is actually in the sump and don't remove the fill plug unless the engine is running. Or it can get very messy;)
