Dme failiure

Hi i want to start off saying im new to this forum and sorry if im in the wrong section. I also tried searching online for solution but cant figure it out. So i have a 2008 335i mhd stage 1 almost fbo and when driving home from school today i got on the gas a bit and car started misfiring. When checking codes i had cylinder 4-6 misfire and 30BB dme failiure. Ive already switched around coilpacks and sparkplugs to be functional. I also checked the mosfets in the ecu and none turned out broken. I can't figure out the issue. Any tips or help would be greatly apperciated!

TLDR: 30BB code not coilpacks not sparkplugs not mosfets. What could be other causes?

Better to look on the motor sub forum or general forum
this is suppose to be for entertainment electronics.
There are also boards devoted to just the N54.

I have looked into one but never done it. I doubt it would be the cause of the codes though.
