If there was a misfire code that popped up, would you just replace the spark plugs and maybe ignition coils? I replaced the spark plugs at 40k miles, so it's only been 20k miles, doesn't seem like much at all. |

60k now then, if it comes up again then yes the ign. coils may be starting to complain and they're not that expensive. Last edited by M5Rick; 12-28-2019 at 01:22 PM.. |

9307A1 - my driver's door comfort access doesn't work anymore (I knew this) a couple codes referring to a CAN timeout (Info E14413 and Info 482740). Seems like there is some lag in time for communication between the DME and another system of the vehicle. Is that something to be concerned about? Weird that i got the CEL back on though. Maybe i have to drive it 50-100 miles?? |

I'm so tired of these "ghost" error codes. I once had BMW do an inspection and the technician said he got like 15, insignificant codes that don't even mean anything lol

Update:
For the below codes: 118401 - Mixture ECU: Mixture too lean, large deviation 118010 - Mixture control, across the databases: mixture too lean Turns out i needed a fuel injector cleaner. The car was registering too much air and not enough fuel. Once i cleaned it out, the above codes went away. Just in case anyone gets the above codes. As for the misfire code, i have no idea why i'm getting it, there is literally no misfire at all. My breather hose was a bit loose so i snapped that back into place. |

So my CEL came back on and i failed the emissions test for my inspection. Looks like the fuel system failed emissions. Any recommendations? Could it be a bad oxygen sensor? I checked my air filters and it looks completely fine. It's not dirty and i made sure the filters have no cracks or holes.

Another poster mentioned it,you have to look down behind the fuel filler pipe rubber grommet.He said there's a breather pipe there..it's a tight fit though.

Update here: i checked the breather hoses and they were a bit oily inside and around the edges so i cleaned it off. CEL is off for now, hoping it doesnt come back.

Update here: i found the issue that was causing the CEL. It wasn't really the breather hose (at least not the only reason). My spark plugs were not "cold" enough to jive with the software tune and BMS intake that i had. I changed the plugs and cleaned the breather hose a couple weeks ago and haven't seen the CEL since.
