Need some help with Codes

MGallop · 01-14-2012, 04:57 PM

just did a scan and got these 2 error codes, and was wondering if someone could point me in the right direction on whats going on and what they mean...

My car is a 2012 n55 w/ mods listed in my sig.

277a (Switch Break)

278e (Diff. Pressure Suction tube)

Any help is GREATLY appreciated.
Thanks guys

cleared the codes, but even with auto clear on.. the 277a code still manages to pop up...

I'd say it's about the brake light switch (see http://endtuning.com/bmwcodes.html), the sensor activated when you de/press the brake pedal.

Just my $0.02

take out the JB. dont be a retard and have them red flag your car.

Its going to a SA who is mod friendly, but will try to see if i can remove tonight.

upon removing my JB, i found that my MAF connector had a wire pulled out of the harness on the JB.

it was the red wire, so not sure what that wire does, but probably why i had thrown the code 278e. I'm not positive on this, but it would make sense.
