Well, playing the bongo on the taillight is not a longterm, viable solution. Neither is having the dealer swap the hardware every other month because they obviously don't have an effective correction and BMW AG will simply just keep kicking the can down the road until your warranty expires soon and they are no longer obligated to deal with this anymore. But that doesn't matter because I'm positive every single 2 Series taillight on planet earth ever since the beginning of time is not defective, this is a programming error. Recheck the coding, maybe whatever you changed wasn't properly saved or have one of the vendors do remotely do it for you, you apparently missed one of the parameters required… I had someone with the same issue with a M240i claiming he "coded" the lights properly, come to find out none of the parameters I suggested actually changed or was saved properly and we just wasted days going around in unnecessary circles. I'm a kazillion 100% sure this is why your are experiencing this "flickering" because I recognize the flickering prior to adjusting the turn signal (LED/Incandescent) coding. *Disclaimer* This is merely just a friendly suggestion, you can ignore all or some of it and do as your please with your vehicle, however you see fit. |

I've done the coding and all it did is prevent lamp failure warnings. The lamp still fails but now the car doesn't tell me. Even if i unplug the entire tail light - no warnings! I don't mind it too much at the moment, it's on the to-do list though. |

You are doing something wrong with the coding. LEDs lights are not design to bounce back any errors, on all vehicles LEDS, they are programmed to disable the bulb check and set to LED, hence the lack of feedback. I'm not there to hold your hands and find errors of your ways, so I have to give you the benefit of the doubt and assume it was done correctly but common sense will tells us one thing, not every single taillight they replace on your vehicle is defective, that's an impossible odds.. Process of elimination, there is something else at play here.. Anyways, good luck with your resolution but I suspect this/ these threads will live on forever. https://www.ecstuning.com/b-genuine-...-kit/92lrfkt2/ |

First, let me say that your contributions on this forum and topic are definitely valued and helpful. The coding will help the majority of people. However, you're not an engineer and don't have much electronics knowledge. I would be hesitant to speak in absolutes when there is plenty of evidence to the contrary. Design flaws do occur.

This coding disables the warm checking in order to stop the "erroneous" errors. But this means if you have a actual turn lamp fault you don't get informed. That's why i tried unplugging the tail lamp and turning on turn signals - no lamp fail warning. |

I need to really test it out but I think mine is similar to giving it a tap and works, saying this because turn car on on issue, drive around and car hits some bumps and stops working then sometime later during the drive works again (error still there but no rapid flashing).

Everything looks good to me regarding the coding.. I apologize for assuming your did something wrong regarding this step but I still have a really a hard time believing that all these taillight hardware that is being actively swapped with the most revised version is the culprit..
I don't know if it would be too much but could swap the taillights from left to right or vice versa to see if the issue persist when you mismatch the taillights to the signal/harness and maybe form a process of error/signal elimination.. This sounds more like LED resistor issue, which disabling the bulb check should of eliminated it, since with the bulb check function is no longer seeking an error and it just sends a steady flash power signal to activate the turn signal function, without the need for power modulation. Allow me to look into research this a little further but there is only so many parts working that could have a hiccup, triggering this error. So it's only a matter of narrowing it down. |

I hope I don't jinx myself again, but after disconnecting the tail light, cleaning the contacts and reconnecting it's been working fine for a week...

I get the feeling disconnecting/reconnecting fixes the problem for some time, and then it recurs, since many of the forum members who've had their lights replaced reported the problem subsiding for weeks or months before it ultimately occurs again.

I had to had some service done at dealer so mentioned the tail light, they checked the connection to see if there was any rust yada yada and they are going to get me a new tail light (yes it will probably do it again in a little bit but still have warranty so gonna let em do it). But after that there was no tail light error for a week or so but now its back

First replaced driver side months ago now passenger side, like others have said it's documented, dealer noted the code because it (happens) no n then and of course at the dealer it's fine

I just got the rear turn signal failure in both tail lights. Both blinkers work but flash very quickly. Has anybody with replacement tail lights reported the issue returning?

I just had my passenger side rear taillight throw a warning. It does the blinky-blinky muy rápido. My service adviser seemed not-at-all surprised.
