N55 readiness monitors reset after stopping
Hello this is my first post so I apologize in advance.
I have a 2011 335i with jb4 and stock cat. Map 0 At first I was having an issue with p0171 ( permanent code) but I was missing an intake tube gasket and after installing, switching to map 0 and clearing codes, I havent had CEL come back on after about 500 miles of driving. I'm using a generic innova scan tool to check for codes and readiness monitors but after trying to complete a drive cycle I noticed that while driving my cat, and sometimes o2 and egr would complete but after coming to a complete stop, they would reset. Is this normal? Do I just have to keep driving until they stay complete? After checking my car now my cat is complete, so I'm guessing I just have to keep driving? I just want to verify it's not my jb4. Also I still have the p0171 come up on the scan tool but no CEL. I'm curious if anybody has more info about monitors or permanent codes. Going to keep driving in the meantime. |

You have a problem - P0171 is bank 1 too lean - you probably have a leak in the intake. Conceivably, this has something to do with your OBDII monitor problem although I can't tell from your description what is actually happening.
But regardless, attend to this P0171 problem, don't just keep driving. Edit: unless you never cleared the code after the "repair". Just not clear what you did or didn't do and what order you did or didn't do it in. |

To be clear my p0171 code was caused by missing this gasket. 13717599292
