W210 "Hydraulic" reservior??????????

[Philip1972]

Hi again

Under the wife's W210 E320 CDI bonnet, on the right hand side as you look at the engine, is quite a large reservoir that says "Hydraulic oil" on it. I am guessing that is for the power steering, but I have never seen a clear reservoir for that, they are usually black, so wanted to check before I top it up......

Any ideas?

Self levelling rear suspension on the 210 estates uses hydraulic fluid.

It's for the self levelling suspension , uses ZHM mineral oil , which should be changed periodically to avoid trouble .

Oh sh!t really? Never changed mine, although I did buy a litre and top it up not long after I bought the car.

Does this apply to the S211 also?

Thank you! I will have to go back to the Merc garage....again lol.

Or can I get it elsewhere?

EuroCP certainly used to stock it, you can find it on Ebay etc.

No - that uses airbags for the rear self-levelling.

And it's for the power steering too, if my memory serves me correctly.

This model shares the SLS fluid with the Power Steering fluid, from the one reservoir.
MB's fluid spec. is stated on the cap.

Mine runs on generic ZHM, though...
