For the cross-linked reference record, Vetaid replaced 'all' his powersteering fluid using the following method:
- E39 (1997 - 2003) > HELP!!! Power steering pump drain plug locatation for bleeding

- Disconnected 13mm bolt that holds two hoses at coil over BUT didn't removed them, while holding top one I just removed bottom one (that goes to reservoir and need to be replaced), got some fluid out but not much.
- Put new ring and attached new hose to its place
- Cleaned reservoir all hoses from mess
- Re-installed reservoir and added new fluid
- made about 10 turns, almost all fluids gone so I added some more to the almost MAX and made same 10 turns but this time level was the same.
- Cleaned everything and hurray - my first serious DIY done with success!!
