Thanks in advance!
I'm not a Mercedes mechanic or expert. In my experiance to "Bleed or Purge or Burp" a cooling system, First you must find the "Highest" point of "Flow" usually the upper radiator hose at the radiator. Losen the clamp (sometimes just doing that will releive the air) sometimes you must loosen the hose to get the air out. Good luck on your "Fix". Let us know how it went.
