Subject car: 2002 E320 wagon

I am trying to sort out various fluids on this car and was sent a suspension fluid which does not appear to be the correct oil. Do the power steering and the load leveling systems share the same reservoir on this car?

I came across this info contained in the "Factory Approved Service Products" (dtd 10.2000) which states the following:

"Hydraulic Oil P/N 001 989 20 03 10
For tandem pumps with common oil reservoirs for steering and level control in E-class, 1996MY and newer."



It looks like this fluid is dealer-only. Thanks for any insight.

 

Can anyone identify the power steering dipstick in these photos?







Thanks.

 

you got tandem pump and i never see a 211 wagon yet.

better follow that hose from the top of power steering pump to find if they share the same reservoir.

 

thanks, sleepwalker. I have tried to trace the route of the hoses. It does appear the PS hose travels underneath the large reservoir that is traditionally the suspension reservoir. I am going to remove the lower plastic panels to verify the hose paths...it's impossible to see where they go when inspecting from above.

I have contacted MBz and they let me speak with the 2nd tier "uber-Specialist". He claims there is a separate dipstick for the PS reservoir but it's not where he describes. I believe the reservoirs are one in the same.
