Hi, my name is***** you are hearing air hissing from the left rear and the car is leaning to that side you will need to replace the left rear air spring.

If you post the last 8 digits of your vin number I can look up the part you need and send you a link to a replacement air spring that is less expensive than the Mercedes springs.
