Unfortunately they don't have OEM Hydraulic fluid 001 989 20 30 10 (Fuchs Titan ZH 5364 B SL) :( You can find it in MB dealership only...

Here - go to these guys. Good place. They have both the Febi-Bilstein and MB OEM Hydraulic Fluid for much cheaper than dealer, and will do free shipping if order is over $50. Select your year/model and look under Fluids and Chemicals category:

I asked those guys as well (also called to Importec and local parts vendor). They had old, mineral type of Hydraulic fluid (000.989.xx.xx.xx), which perfectly compatible with W124 and not compatible with our synthetic base hydraulic oil. :(

Wow, did I misread the part number on the reservoir. Thanks, I'll submit a post to see if I'm ok with the quart of Febi I added last summer since I have synthetic and mineral oil mixed in there now! Don't really know enough if that is ok or now. I know using anthing other than synthetic in Transmission is not good. Interesting that ******** and other sellers list that as an ok fluid for w210's.

one of the supplemental books I have for the 2002 car confirms that the FUCHS fluid is the only one suitable for the car...it agress with the number printed on the fill cap of the reservoir.

I have 1992 300D 2.5 turbo which has hydraulic fluid resivor up front behind headlight on drivers side. This fluid supports a locking rear differential that stops the rear wheels from spinning. Adding to what others have said on this posting, a third use for hydraulic fluid in a benz.
