    Hi all

    Newbie here.

    I just took delivery of my 2010 ML350 very pleased with it but it did come with a problem which i was aware of.

    The power boot opener does not work.

    I have done a little bit of poking around and found the pump this runs when the button is pressed and it has hydraulic fluid in it. I then checked the opening next to the boot hinge looking through into the headlining to see the piston in there that should move the boot lid, pressing the button this does activate and move the piston back and forward but nothing happens with the boot lid moving.

    Looking through the paperwork it did recently have new struts on the boot lid, are the struts different for the power boot opening type and the standard close type? I just ask this in case the standard type are stiffer than the power boot struts which is preventing it from opening and closing.

    Other than that i am not sure what to look at next to get it working.

    Any advice on this is very welcome
