!!!! Brake Fluid flush DIY - How many liters?

Doing a brake fluid flush right now, deciding whether or not I should go back to the store to get an extra liter. I've usually only used 1liter in the past for my other cars, but the e65 is a much larger vehicle.

How many liters will I need for a proper flush?

I know the 7th has different brakes but I used only 750ml, tops, to flush my brakes, with ASC. same with a DSC equipped 540.

hrmmmm... Anyone with an e65 know from experience?

1 liter - or if you want to over bleed then 2 liters. but you will end up with only 1 liter in the car.

I just did this last fall and I used 1 liter. I even had a little left over and flushed a lot just to make sure there were no air bubbles in there. Good luck.

Yep, I used exactly 1 liter, flushed it quite a bit also. All of the lines had brand new fluid coming out with no bubbles
