Help codes keep coming back!

Car: 2007 335i coupe
All major recalls have been done. Injectors, fuel pump, water pump etc plugs and coils are relatively new aswell.
So lately last month or so, my engine light keeps turning on. Same codes keep coming back.
2DEB power management, vehicle wiring system control
29E1 fuel mixture control 2
29E0 fuel mixture control
2AAF fuel pump, plausibility
If I clear them, they just randomly come back while I'm driving, doesn't matter if I'm full throttle or just cruising. My mechanic told me it was the 02 sensors but he was wrong and I wasted all that money for nothing. Any ideas? Thanks

The thing is, my battery is brand new, I just got it this winter. It's oem and I made sure my mechanic programmed it.
