How much volume of power steering fluid do we have in the E39?

How much, in total, power steering fluid is there in our E39s.

I scoured the Bentley and owners manual and didn't see this information.

Here is what I have so far in the E39 fluids summary.

What else do we need to say about power steering fluid?

- Power steering: Dexron III ATF (realistically, Dexron VI ATF because Dexron III certification is no longer available from GM) Bentley page 020-20. [Volume: It has been said to be just under 2 quarts; I used about a quart to flush twice just my power steering reservoir using a turkey baster to remove fluids out the top.] Note: I6=rack and pinion attached to an aluminum subframe, V8=recirculating ball and nut attached to a steel subframe. Replacement Interval: Bentley says it's "permanently filled"; but most of us would suction out and refill the reservoir with about a quart of fluid every few years because it's a hygroscopic fluid and the permanent filter on the bottom of the reservoir doesn't prevent the fluid from becoming dirty. Some even replace the reservoir in order to have a new filter. Most also replace or cut off the tip of the bottom hoses whose clamp often allows leaks.
