Power Steering Hoses

[brosher]

These are the reservoirs shown on realoem under my 9/95 US 540:

#1 is base, #2 is self leveling


And this is the one I have It is for cars w/ ASC:

Mine is #1. But it also has ASC.

Sorry about the mixup on the ATF/Pentosin thing.

I also have #1 (CHF11S) with ASC, just for informational purposes.

Mine is #2, it has ASC+T but non-self leveling and requires CHF11s. The Bentley manual is not entirely accurate.

Build date 5/93, USA version 530i.
My Dad's is identical, build date 4/93, USA version 530iT

No dipstick, large reservoir, screen strainer etc.......................

I think it may have something to do with the ASC. The plumbing from the ASC unit is directly linked to the reservoir.

BMW sure went with all the types of hydraulic fluids they use.

My car is from the German market (imported by the PO) and uses Pentosin 7.1 fluid for the power steering.
Sure pays to check what fluid you need before working on it...

Well, so far no one has the #1 reservoir with self-levelling. I don't know if I have ASC or not. Is the little switch next to the Automatic shift lever with the snowflake an indicator?

[Blitzkrieg Bob]

ASC, no LAD and uses reservoir #1 w/ATF.

I don't think ASC uses the power steering for control, I think it works via the brake and throttle control.

Pentosin 7.1 was used on early production years, later it was replaced by CHF 11S. But it is not mixable.
I have # 2 and I have LAD

I have #1 no asc no leveling
