I think your turbocharger hose has split.That is what I would check first.

Thanks for instant reply... Hope so that only hose broke or detached. That is not EGR symptoms?
I connected hand obd reader and also no error code. Strange... Cant wait monday, **** happens to me always by the weekend

Problem solved

To answer myself...

Lower air intake throttle broke... Next to MAF sensor.
Lucky me, that is not expensive repair.

I learned that this part A6400901170 is not w169/w245 part, MB take it and share it with w639/w640 (Mercedes Vito)...
