[Bbmw535]

Hello everyone,
Week ago noticed this loud noise coming from MAF sensor area. It almost sounds like bunch of bees trapped in the intake box/tubing.
I used Carly to scan for codes and received several different error codes mostly for "charge air temp sensor" which might be MAP sensor located on charge pipe I believe.

I pulled out MAF, MAP and another sensor that looks identical to MAP sensor located on the intake and cleaned them with throttle/maf sensor cleaner.
Now seems like noise doesn't happen as often but its still there.
It believe it only happens when cruising at low speed. As soon as I accelerate harder it goes away. Sometimes I can drive for 30 mins and its ok but sometimes as soon as I take off it comes back.
After some research people are suggesting cleaning idle valve, checking for vacuum leaks, pcv valve I tested and looks ok.
Has anyone had this issue with their f10 535i ?
Check engine light is not on yet but trying to prevent a bigger problem tomorrow. I forgot to mentioned that car performs just fine. Cant notice any issues.
Your input and help would be greatly appreciated!!
