F30 335i Does not start after JB4 Stage 2
Hello Fellows.
I need your help. After installing my JB4 stage 2, my car got into limb mode and iDrive gave me a Drivetrain fault alarm. The car became very weak and almost didn't move, so I connected the PC to the JB4 software and, and was unable to get connect to the box. I disconnected everything and re-connected, the performance got even worst but in that time I was able to connect to the JB Box and read the following codes. 1B5202 No Description Found 1B5402 No Description Found 1B02AF No Description Found 1F051F No Description Found 051511 No Description Found 272F13 No Description Found 000000 No Description Found 0000F1 No Description Found After that I decided that was time to remove the JB4 and start troubleshooting because my car was not even starting. IŽll upload a video of that. I've tried to remove the alarms using the Tool32 fs_loeschen_funktional, but the alarm remais active, the car makes a dong and the drivetrain malfunction alarm comes back. I don't know what to do. My car is still under the warranty, but I want to be prepared before taking the car to the dealer. Thanks in advance ! |

None of those are codes I've seen before. I have no idea what you've done but first step is to read codes with a BT cable so you get descriptions and then post those on the n54tech support forum for professional advice.

The sheer number of issues with BMS products is getting a little hard to ignore, as much as I back them and still plan to buy a JB4. A few here and there you can shrug off and chalk up to user/installer error, but not when it's a constant barrage. How long can one defend a product before it becomes denial?
Hope you get your issues resolved, OP. |

Your car is not starting even after you removed the JB4?
And did it all happen right after you installed the JB4 or did you have it on for awhile? |

I still don't understand why people ask for help on this forum as there is no one here to help them. Only me to remind them to go to the source for assistance. Mike |

Only people I see truly backing the JB4 are the sponsors who sell them. Seems like a high probability of trouble for people who are concerned about warranty and can't afford a catastrophic issue like this one. Car not starting?? Clear signal of a $3XX product that is poorly designed, which is directly correlated to no warranty offering.

Mike, I'll follow your advice and create a topic on the other forum.
But I know that knowledge is everywhere, and I am sure that there are several stranger here that are willing to help and exchange experiences. |

The engine starter works and the car tries hard, but it behaves almost like the car is out of gas. |

Came back and started troubleshooting. Connected the jb4 to the pc and selected map 0, after that I saw that the car was getting worse. Disconnected everything, reconnected and the car remained the same... The error codes I listed before kept showing up and I couldn't find it on the internet. And suddenly the car was not starting anymore. Removed the JB4 and realized that I needed |

I don't think #3 counts as a JB4 problem when the user added 100% water to his meth tank and tried to run the meth map lol. And other links seem like they are user error.
You also have bring in the fact that some of these problems could be from the car and not caused by the JB4. |
