yes, i'm curious as well. What kind of effect will it have after a software upgrade? thanks in advance. I'm about to order my x5 so i'm trying to see if the laser lights are worth it. if not, i'll eliminate the executive package. what kind of increase in output will this coding have on the normal LED lights vs Laser? |

When you code anti-dazzle you're doing two things. I don't know your baseline knowledge of coding so I'm going to boil it way down - I'm not trying to offend you.
The first thing you do is you remove the "decode anti-dazzle" option from the car. This essentially is telling the car that you have anti-dazzle. this is called VO coding. The second thing you do is you "CODE" all the ECUs that control anti dazzle - because according to them, they still think the "decode anti-dazzle" is still one of your features (VO coding), so you have to update the ECU for your new feature list. This is called FDL coding. VO coding is the parent code - FDL is a slave code. So if you change a VO parameter, you can simply update the FDL and it will follow the VO code. Alternatively you can simply FDL code every module in every ECU that's required to achieve the same thing. Luckily the anti-dazzle is a VO code parameter so you don't need to FDL code each module. Since you have gone through the steps to remove this feature, the car now thinks anti-dazzle is part of your option package - so every subsequent update will follow that parameter. The optimization is where FDL coding is requiring. Since FDL is a slave to VO, any changes you make by FDL will be lost when BMW updates the software. I hope this made sense and was easy to understand - there's a lot more detail to it but this is the broad brush of what's going on. |

Seems to me that based on VTENGR quote below, if the VO code for anti-dazzle is done, it will be permanent even after a software update push. Because he said VO is the parent, and then he said "so every subsequent update will follow that parameter: "Luckily the anti-dazzle is a VO code parameter so you don't need to FDL code each module." "Since you have gone through the steps to remove this feature, the car now thinks anti-dazzle is part of your option package - so every subsequent update will follow that parameter." |

Thanks to everyone for all of the detailed explanations on coding. I am coming from a lifetime of Acura ownership so BMW ECU coding is new to me.
But being a tech geek I understand what the issue is. Question. Without coding, what then is the advantage of the laser lights vs standard LEDs? Is it just that the high beams are a bit brighter on the lasers? Are the low beam outputs the same? I’m asking because the only reason I wanted the executive package was the laser lights and my perception that they’re significantly better than the stock LEDs that some with the premium package. Looking for all opinions. Thanks so much. This seems to be a really passionate owners group. Similar to the groups on Acurazine. |

Laser lights have 4 projector low beam lights. Standards LEDs have 2 projector low beam lights and the two inner headlights do not light up. The daytime running light graphics also look completely different. |

The laser lights also give you cornering lights and the non-lasers do not. As far as performance goes, the laser lights are brighter in high beams even when the laser aren't engaged. Once they are then not only are they even brighter but also more focused on the road ahead. The non-lasers are brighter in low beam, that is what causes the glare and why they are rated poor by the IIHS.

Since the as delivered vehicle doesn’t generally make changes to the module that disables the functionality of the anti-dazzle, when new software is installed, it doesn’t overwrite it to include it again...but, it changes everything else, which has some of the optimization ‘switches’ in it, so while some parts of it will still work because that module is still not there, the optimization bits in the modules that are changed, are reverted to factory, so must be redone. Some places will do that for you as part of their ‘package’ price, but until that’s done, you won’t have full functionality any more.

the low beams are brighter on the standard LED's? how's this possible if the inside bulb is a dummy on the LEDs vs the lasers? Low beam is most important to me for daily driving. are the standard led's higher output in terms of lumens and distance vs the laser low beams? |

In theory it should eventually be three times a year to mimic their major software release schedule.

Because the anti dazzle adjusts the projection at all times, your car should run high beams exclusively at most times. To be fair mine haven't been coded yet so this is a bit of theory based on an understanding of the system but hasn't been tested in the real world by me.

I live in a quiet neighborhood and even though are streets are well lit, around twilight the auto high beams will usually kick on if there's no cars around. Leads me to believe if I had anti-dazzle and there were cars around it would still kick on and adjust the projection accordingly. Hopefully someone with first hand knowledge can shed some light (LOL...see what I did there?) on this.
