Whooshing/hissing Noise while steering stationary? - with video/audio
Hello everyone,
please excuse my bad English, I sometimes work with a translator because I'm from Germany.
I drive a 2012 SLK 250 CDI, but since this is related to the W204 in many areas, I'll post my question here in this forum because there may be more people here who may have heard something like this before.
To make it easier to understand, I filmed and uploaded the whole thing.
When I steer to the left while stationary, I hear a kind of hissing/whooshing coming from the front of the car.
The noise can be heard on the inside of the steering column/footwell, but also on the outside next to the two front wheels.
This hissing occurs primarily as soon as you turn the steering wheel to the left faster.
Here you can hear the sounds well from the outside:
Here you can hear the sounds from inside from two perspectives:
The freewheeling of the alternator has already been checked in the workshop and found to be OK.
The oil level of the power steering looks OK based on the dipstick on the cover.
As I have never heard a noise like this I would be very grateful if you could take the time to watch my videos and give your guess or opinion on this as I have been desperate for a solution or explanation for the noise for quite some time seek.
Maybe you can test/check that on your vehicles for comparison.
Thank you in advance and best regards

PS: The noise occurs constantly in the above situations and is therefore independent of the engine or outside temperature and it is not the familiar noise at the end stop of the steering, there is a slight whine from the pump, which I consider normal. It is therefore not a howling or yelping that one often reads in relation to the power steering.
