multiple codes please help

etrilla81 · 03-07-2023, 07:55 PM

hello new to the forum I got a 2012 335i N55 basically stock minus BMS intake, GoFast Bits diverter spacer and catless downpipe.
I heard a slight poof from engine area about 2 months ago and then the dreaded half engine reduced power message came on, replace valve cover, boost solenoid and MAP sensor but no joy.
codes that are coming on now...277A 28A0 29D0 2C57 AND 2C90 any thoughts ?

sounds like you should smoke test it and check intercooler piping.
