E430 Power Steering
 

I have a 2000 E430 . I want to add a little Power Steering Fluid because it is a little low .
1 ... I want to confirm that the P/S reservoir is under the black cover with the star .

2 ... I want to know what type of P/S fluid to put in the car . Can I get P/S fluid from Auto Zone or do I have to get it straight Mercedes ? Thanks

There's probably a number of black covers with stars. I think your reservoir is on the pump, which has a nice large pully. Hard to miss.

MB recommends MB fluid for the later models. Get out your wallet, because they're proud of it.
