There is a hurrible noise from the rear as if somethings are rubbing each other

Do you have a brake light on too? If it's just the rear brakes making noise you should be able to drive it in to a repair shop. If you suspect there is another problem you may consider towing it into your Mercedes service center.

If you can see underneath I would check to see if something looks broken or out of place. If not then call Contra Costa Auto Service and make an appt to have Adrian take a look at it. (925)798-1205. GL
