air leak on braking

[greekmercedes]

my w203 c180 has a funny problem.. when you brake hard the engine starts hunting and sometimes stalls. a while ago i was advised that they have a common fault a "part load ventilation pipe" splits which causes a air leak. This was replaced two months ago but i'm still having the same problem.

The fault must be in the 156 or in the booster
