Air mass meter, signal: electrical fault
Code: 00277A

Intake air temperature, electrical: short circuit to positive
Code: 0029D0

This is on an E92 N55. Any help would be really appreciated!
I don't have my manual handy, but at least your second code looks to be missmatched to the description comparing to a quick google.

Looks like 0029D0 is misfire on cylinder 4
