Glad to hear.

[@moniquejalbert1413]

Is this an accumulator for the ABC or is this for the power steering? I keep getting two different parts unless they are one in the same

[@DEEuroworks]

@@moniquejalbert1413 should be the same part. Mercedes dealer sells it.

Do you perhabs have some video of the sound it makes?
I think its the pulsation dampener but cant find any videos of the sound of it

[@DEEuroworks]

@@Jerry.V I don’t, its more of a feeling than sound, kind if like bad motor mounts but only around 1500 rpm.

[@Jerry.V]

@@DEEuroworks weird question, but does it also make kind of a whining (supercharger whining) noice when driving low rpm? (Below 2500 rpm)

[@DEEuroworks]

@@Jerry.V hard to tell without seeing your car, but most likely.

[@Jerry.V]

@@DEEuroworks yeah true, but what I ment when you replaced it, did it make that kind of sound

[@DEEuroworks]

@@Jerry.V Yes.

[@edgarquinonez7864]

So if theres vibration and that skretching sound at low RPM is the pulsation dampener?

[@DEEuroworks]

The pump might be bad too too if it’s making noise too, but if it’s mostly vibration, typically motor mounts or the dampener

[@edgarquinonez7864]

@@DEEuroworks so I replaced the pump that's on the front driver side, some of the noise went away, but I still hear a small noise at low RPM when I stop at a light and when I turn on the car I hear that scratch noise. Also after I replaced the pump I was touching it and I felt the vibration on the lines and pump

[@DEEuroworks]

@@edgarquinonez7864 did you use a new oem pump?

[@edgarquinonez7864]

@@DEEuroworks yeah I did brand new from mercedes, for what I'm reading and the symptoms I feel like the pulsation dampener is bad too

[@DEEuroworks]

@@edgarquinonez7864 ok. New pump typically comes with the dampener on it. Was it on it?
