Power steering Fluid for W210

[welland99]

My power steering fluid is a bit low (just under minimum) and needs topping up, but I can't find anywhere a specification for the fluid I need. I have searched the handbook, but cannot find any mention of power steering at all.

I have a bottle of Comma power steering fluid that i used to use in my last car. The bottle says, "...suitable for use in most power steering systems." But the bottle gives no further information about it's specification or suitability.

Should I just bung it in? Could it do any harm?

I changed the fluid and use the Mercedes one. Its not that dear, for less then a tenner I would stick to MB if you want to top up.
The part number on the bottle is:
A 000 989 88 03
Sold in half litre.
