C220 no power and smoking

[duff]

Hi every one I'm sure this has been done before.
I have a w203 52 reg c220 while driving it just lost all power still driving but not well. I plugged in icarsoft only fault was p0100-064 b1/5 (hot film maf sensor) plausibility 3. I've replaced maf sensor removed egr and cleaned put vacuum to egr and it opened ok, then I checked turbo spinning free no play when you start engine actuator moves if you remove vac pipe it returns. Still no power no kick down. Any help as what to check next. Thanks

Check the boost hoses carefully for leaks. Loss of power and black smoke are both symptoms of boost leaks.

Thanks have checked but will check again. One more thing if I unplug egr it runs slightly better but still undrivable

Don't know how I missed it! Bottom intercooler hose out I squeezed and pushed/pulled everything the one joint you can't see easily popped out but was jammed so felt good.
I decided to remove all hoses to properly check and hey presto feel like such a wally
Anyway sorted thanks a lot
