Hi guys
I've noticed something somehow a bit odd

When i have my fog-lights on my anti dazzle headlights behave as US specs on/off high beam. My car is a US spec with headlights coded.

When i switch them off it functions as the anti dazzling would normally function in Europe

Anyone faced this or knows how to fix it ?
Or this is how it's actually supposed to be?

How does anti dazzle work? I have my lights coded so I can use fog lamps with high beams. In auto mode, my headlights switch from low to high and back just fine. However, people are always flashing their high beams at me even though mine are not on.

Given the height of the X7, and the fact that it has 4 lights on for low beams (2 on each side) many folks thinks the high beams are on when in fact they are not.

I've only gotten flashed less than a handful of times in the last 6 months. I just flash them back to let them know my high beams aren't on.

As far as anti-dazzle, it's a fancy way of letting the led lights light up certain portion of the road in front of you without blinding the cars in front or the on coming traffic. the led lights will move around and shut off as necessary.

Search for it on youtube, there are a few videos demonstrating it. The HW in US cars support it but the DOT laws don't allow it so BMW codes it off. It can be coded on via e-sys.

Perhaps I'm just having a bad day but can people look at least a little for answers before asking questions on here. BTW How do door locks work?

The same goes for those who respond... Or was that a reaction to 812Superfast 's question?

Don't want to be rude guys, but i think none of you got the OP's point. He hasn't asked for how Anti-dazzle lights work, he asked whether that system supposed to be working with fog-lights turned on or not.

I have EU version so i'll check this from the point of view of a vehicle with native implementaion...

Yes, that was my knee-jerk reaction to 812Superfast. If you turn your fog lamps on in US the anti-dazzle goes away.

Anyway around that ?
By Coding or is that a HW limitation on the US headlights?

[Nath4n]

Ok, just to let you know that EU version does that too.

This is a result of coding on fog lights w/ high beams and anti-dazzle.

If you have fogs on, the coding allows them to stay on with high beams, but that freaks out anti-dazzle.

Turn off coding for fogs with brights, and then anti-dazzle works. But fogs will turn off when anti-dazzle is in effect

That's not true.

Fog lights work fine in conjunction with anti-dazzle. They will turn off as designed when the antu-dazzle feature is in effect.

This also explains why fogs w/ brights messes up anti dazzle and they revert back to simple on/off high beam.

Basically, you got to choose. Fogs with brights or anti-dazzle.

Or, just accept that if you want anti-dazzle to work as designed, don't turn on your fog lights.

I have stopid question, does 2019 X7 40i have anti-dazzle feature? If so how can I find out? If it's decoding VIN, what I need to look for?

All have them standard

Is my anti-dazzle feature active or it needs to be coded on?

In the US they are disabled from the factory and need to be coded on.

To be clear, there is a difference between "No Dazzle", which every X7 has off the line, and "anti-dazzle", which has to be coded for USA models. I often get the two mixed up.

Yes I was readings the other threads on coding Anti_Dazzle feature by activating the capability. It appears Bimmercode apps can not be used to get full feature.

Per other thread "even if you activate the feature using the basic functionality just by changing 2 BDC 1DF8 FDLs
C_HBA_DIM_ENA --> enable
C_HBA_GFHB_ENA --> enable
Just these values give basic feature (they may turn off a lot), but for bimmercode users it might be at least a small improvement over not having it at all"

Since there are many other parameters need to be changed to activate the full capabilities of anti_dazzle, I may get help from r33_RGSport to remotely code the anti-dazzle lights.

100%. He did mine and was amazing…it takes about 45 min and he remotely logs into a computer which is attached to your obd port. Feature is amazing.

I've been trying to address this issue for quite sometime now.

I have anti-dazzle and VLD coded, and then I also coded fog lights with high-beam.

I found that when fog-lights are manually turned on, the headlights do not work anymore in the anti-dazzle mode, and instead switch to regular US spec (on/off only).

The best solution I found is to give up on the fog lights and only use them when I am in town to not prevent anti-dazzle. This is also how it works in Europe. When Anti-dazzle kicks in, fog lights turn off (unfortunately, u then have to turn them on again later if u need them). I think someone with time and experience in coding can figure this out.

Does 2013 models have anti-dazzle headlights?

There was no X7 back in 2013 .....
I think you are referring to 2023, in which case, yes '23 does have anti-dazzle hardware that's activated for ROW markets, not US though. And coding is not possible as of yet, as the car has to "phone home" to get authorization to code.

Haha yup I meant 2023!!
