Coding for no dazzle headlights?
Was anyone in the US able to enable these?
On my build sheet I have: Decoding for no-dazzle hgh bm Hoping I can recode the decode. Last edited by MPR; 04-14-2022 at 07:46 AM.. |

Given it's decoded on the build sheet, I assume it can be recoded. Was just curious if anyone has done it yet Last edited by MPR; 04-13-2022 at 06:30 PM.. |

Can you post pics of the data labels on your headlamps?

I don't have my car yet, just came across this on my build sheet and was curious. Audi has similar technology, also disabled on US cars. It's pretty cool if you can get it to work.

I checked with CMB and they do not support the G42 right now, but might in the future. Probably just too new at the moment, but other vendors/freelancers might support it if you dig around.

I believe in general across models. At least newer models with the encrypted ecu’s that haven’t been accessible. There was a thread I’d seen about some coding in bimmercode to do a dumbed down version of the actual No dazzle high beams, but it doesn’t work exactly like the real thing as it’s not the full coding for it.

We don't get the dazzling effect which re-aims the high beams if there is an oncoming car. If there is an oncoming car, the high beams just turn off instead. Which is part of the auto high beam option. Therefore, Automatic High Beams and Dazzling high beams are two separate features. The US only gets auto high beams unfortunately |

Auto high beams means it'll turn them entirely on or off based on what it sees (oncoming cars). Where the decoded feature can dynamically control only certain areas, turning off only where it sees a car (someone that could be blinded) and turns off only those beams of light, leaving the rest of the area high beamed. Watch that video I posted it may help you understand.

The accepted technical term is ADB, adaptive driving beams, and is not the same as auto high beams or even adaptive headlights. Adaptive driving beams are also commonly referred to as "matrix" headlamps. They ARE allowed in the US. For an in depth discussion see the thread i started titled "Adaptive Driving Beams for US 2022", located in the 3 series forums under G20 General Discussion. It has an in depth discussion and review of the 2/22/2022 US Final Rule 40CFR571 (a 111 page document) that revises the old US regs for headlamps. That post does compare the US regs with the Euro ECE regs. Part of the confusion is that the US regs did NOT adopt the Euro standards and kept a relatively low level of maximum illumination allowed for these adaptive driving beams (roughly only 50 percent of that allowed in the ECE standards for much of the rest of the world. The reasoning was rather spurious at best, simply put they did not want to modify their testing procedures in order to test the for the higher output levels acceptable elsewhere. So yes Adaptive Driving Beams are allowed in the US as of 2/22/2022 but must meet the US standards which are not the same as Euro/ECE standards. Much more detail in the post i referenced above. I do have a copy of the US regs if anyone is interested i can email it. |

I don't get what of what I said is incorrect..so they are allowed/legal but not the euro standard that comes with BMW? Same thing, it boils down to them (BMW no dazzle/matrix) not being allowed in the US as of current

It's no biggie, i just wanted to clear up some of the confusion around the new regs and BMWs awfull "no dazzle" term which is close to meaningless. |

The answer is yes, it can be coded with a program called "ESYS," which removes the block code implemented on US-bound vehicles to prevent this feature from activation. However, since the model is new, no one has yet to attempted this but it's all the same.. |
