Maf sensor problems

[25benz]

Hi lads I'm pretty new to the merc of the world but this clk 270 cdi off my dad with a few problems
Inlet port motor shut off
I have ordered the delete kit for the swirl flaps

My second problem is the maf sensor, u cleaned it with carb cleaner didn't do jack to it so I brought a new pierburg one for 57 quid an I thought it would sort it out but no won't clear code with my code reader I'm wondering once I've sorted the swirl flaps problem out will this go away then??
They are my codes at the moment

One fault can trigger all those codes. Check any leaks in boost lines, EGR functioning and valve tightness.

I've checked boost pipes, an the intercooler, I thing it's the swirl flaps that are the main issue the kit should be here Thursday for it so I can delete them I've checked the vaccum on my egr good vaccum I cleaned the egr still didn't change so I brought a brand new one as well just them crappy swirl flaps left
