Mercis is right, try to mess turbo first.
I aready had problems like that in my workshop and the fault was different in all the cases.
Turbo, air pressure sensor and mass air flow meter.
If you need to change it buy it in Mercedes because it is not very expensive and here in Portugal I tried another one that the seller told me it is equal to Mercedes and it didnt work.
