C180 hissing near rear drivers side wheel?

[akz786]

Sounds like the fuel pump, you can hear it all the time, like a light hissing sound....anything for me to be worried about?

TIA

does it go away when you turn off,....

has it got self levelling suspension--

Yes its not there when engine if off, not sure about self levelling suspension, its a 1995 C-Class 180 Auto Elegance, dont think they had that then? did they?

No self levelling suspension on your car , the location points to the fuel pump which can normally just be heard but is not intrusive , if the car is running ok I would not worry it may be normal.
