Help code 2c57...boost leak??? n55

KcN55 · 10-07-2013, 05:18 PM

Hey guys! I need some help with this error code (2C57) boost leak for the n55?. I've been searching and trying to diagnosis it for weeks now. I read all the threads about this code but none seem to be the case. The current mods that I have ; injen intake , catless cat , bms charge pipe and Cobb.

This is what I have have checked out so far:

1.The first thing I did was to check my charge pipe, everything seems to be on tight.
2. I uninstalled my cobb tune, Same code pops up. I'll post some logs up
3. I had the dealer check it out, they blame my down pipe
4. Got my ecu updated by the dealer ..same code
5. Next I plan to check my IC where the plastic pipe connects if there's any cracks.

Any idea? Its half engine light that comes on, not even a check engine light and it only comes on when I start boosting. Could it be the dp? Busted tube? Crack somewhere else? Where else should I look. Thanks. Any help will be appreciated.

Is this a constant code?? Mine was only on the track traveling at 200kph...

Data log with your Cobb AP and find out what boost levels you are achieving, this will give you an idea as to the size of the leak and hopefully what you need to look for.

To me it sounds like the leak even at low boost , check pipes on mods done... Mine is under pressure at 16psi traveling at 200
