N55 Real downpipe CEL fix in the works anywhere?
Currently have a JB3 with a Berk Downpipe. I know the CANbus tool can delete the code, but the N54 actually has a real downpipe fix so that no lights ever get thrown to delete.
Anyone know if there is a real downpipe fix in the works for the N55? |

I believe the N55 Stage 2 (JB4) will automatically discard codes related to exhaust modifications like the current N54 JB4.
I think it's being beta tested, most up-to-date details are here: http://n54tech.com/forums/showthread.php?t=13189 |

yes it will pass for any state that does a OBDII emissions test with a true DPfix (ala BMS N54 fix). Neither I nor Vlaze lives in California

sorry for bringing up an old thread but im just wondering if the JB4 tune has a true downpipe fix or if it just deletes the light off the dash?? I live in Massachusetts where they dont probe. They just do the OBD test so i am a little confused whether or not i can pass with just the tune and no BMS dp fix..
Thanks guys |

Auto-clears. You will not pass a OBDII emissions test with just the JB4.

If you have an N55, your only two options are to get a:
CANTOOL or upgrade your JB3 N55 to a JB4 N55 Stage 2. It's not a fix necessarily as it will only remove the annoying SES light on your dash. -Frank |
