    Hallo all,

    My w204 - 220 cdi has a steering problem. I've change my old pomp six months ago and now I need to change it again. Steering oil is somehow boil ( flow ) and when turn left / right pomp make noise. My mechanic told me to change longer hose and replace pomp again. When we made aeration ( w/o engine start ) big air baubles come out like somewhere pomp absorb air.

    Oil is green and locks clean. No small iron elements inside.
    My opinion is that other part destroy these pomps and I intend to change all hoses.

    Please give an advise.

    Thank you in advance,
