Last week my Auto High Beams went back to US spec. Meaning they just go on and off when it senses a car or oncoming lights. Before this, they were splitting and lowering appropriately with oncoming lights.

I have not had any software updates. I basically get the green "A" next to the headlight symbol and the blue high beam indicator goes on and off as described above or like the US lights are spec'd to do. I thought there are also an "A" next to the blue high beam indicator prior to this, but I can't really remember or say for sure.

Strange. Please let me know your thoughts.

I'm still making progress on NGHB myself, but for it to randomly revert behavior is odd. Closest I've encountered is the arrangement of my iDrive apps keeps resetting in the home menu.

I can attest that the way the symbols appear to be working is correct. The green high beam with the "A" on it lights up to indicate that HBA is activated, and the standard blue high beam symbol lights up when the high beams are actually coming on. To my knowledge this behavior is the same regardless of if NGHB is enabled or not.

Thanks. It's really strange. Right now it's going back and forth from high to low all the time like a US car should. It's annoying after you have gotten used to Anti Dazzle and VLD. Before the high beam indicator and beams were on 90% of the time, but the high beams adjusted individually.

I'm having the coder go back in Sunday.

When you did have it working - were you able to have the setting stay between restarts?
Or did you have to tap the stalk each time you got in the car?

I have to tap the stalk. There is no way around it from what I understand but thanks for the reminder, I'll ask the coder.

That's strange if you have not had an update.

I will recheck mine on next nighttime run, but as of last week it was working. Some initial thoughts - the sensor may be blocked? An unattended OTA update occurred?

Also, have always had to hit stalk to enable - do not believe most 2018 cars have it default to last setting.

Thanks as always. There is no OTA update functionality with a 2018, so ruled that out. I've heard the same about not being able to code remember last setting for ID6 cars. We will see about that tomorrow.

Funny thing is, this morning it seemed to be working. Got some dips and splits. I've thought maybe the sensors are dirty. They are in the mirror right?

Perfect. Thanks for this. I'll clean them, but my car is always spic and span. You never know though.

Just to follow up. Coder went in. Anti Dazzle and VLD were coded on from factory, however he found camera error codes. Cleared them but still not functioning. Trip to the dealer next. I hope it doesn't result in wiping out my coding.

That sucks. My fear is having all the remote coding work wiped out. Good luck.

Yeah that's my fear. Not sure it's worth the trip. I don't drive at night much. I made the appointment though.

Curious if I am crazy here. Can you tell me if your blue high beam light stays on most of the time when you engage the system? As I mentioned, mine now keeps toggling back and forth. It seem to be trying to use AD and VLD but I think the faults from the camera are kipping it, then it tries again. I do see some resemblance of the system at times with the lights adjusting, then it goes to green.

The interesting thing that is making me wonder if I am crazy and the system always worked like this is that the functionality now has the same exact pattern on my daily drive to the gym in the morning. Meaning, it kicks back to green at the same exact spots on the highway and when off the highway. I could have sworn the high indicator was on most of the time and the lights just adjusted or lowered when appropriate. It is driving me nut. My fear is that I will go to the dealer for nothing even though I have the printouts of faults. I would imagine these faults register during rain or poor camera conditions as well.

[Joe-BMW33]

Qsilver7 would you have any input here? Please see above.

I've had that error come up once because of a particularly cold night causing the rear view camera to fog up (once the car warmed up, it was fine) - so just saying, it may be unrelated...

Just to be clear, these faults are not acknowledged to the driver, they stored in the ISTA profile. It's not like I am getting a system inoperable message. I would not even know about this faults if the coder didn't go in.

Joe - my blue high beam is NOT on all the time. It only goes on when conditions are right - which depending on the road may be a lot of a little.

Because of your post, I actually watched it last night and initially no blue high beam for a while. Just as I started to freak out based on your issue, it did pop on and off as the road status changed. I have to believe it is effected by temperature, fog, etc since familiar roads traveled have not always triggered to the same headlight action.

Thank you, this is extremely helpful. You do have AD and VLD coded right? Mine has been working the same way you described. When starting out it takes 30 yards or so to kick in and then it toggles a bit at times. When it is on (blue), AD and VLD are working.

Maybe I just didn't really study it before and am over thinking it. I think the fact that it behaves EXACTLY the same way on my 10 miles trip to the gym each morning in the same exact places and environment leads me to believe the camera is working correctly. The faults above could have been registered during a down pour the night I noticed it went to green. This is what started me on this hunt. I was driving home at night during a down pour on the highway and noticed my blue indicator didn't go on for a while, so I started studying it. Maybe too much.

I also came across this service bulletin which got my wheels spinning more.

It depends on the road conditions, but it does stay on when the high beams themselves are activated, even if they're splitting or partially dimmed. As far as I can tell the blue light isn't impacted by VLD since that's behavior relegated to the low beams.

Are you saying your green "A" indicator switches off when the blue indicator switches on? Because mine doesn't do that unless I manually override the auto high beams. Also not sure if this is relevant but I have the base 6WA cluster, not sure if the full digital instrumentation has different behavior.

The 800A01 KAFAS error does prompt a Check Control Message and doesn't necessarily cause HBA to stop functioning or reduce the functional state.

The other one doesn't provide a Check Control Message and will reduce the HBA function state.

Is there any damage/alteration/contamination of the windscreen interior or exterior within the camera area (incl installed devices such as a radar detector)? Any bugs or debris between the glass and camera lens? Have you had the windscreen replaced?

Thanks for this. No the green indicator is always on. When I push the bottom stalk button for high beam assist, the green light grows an "A" next to it. From there, the blue high beam indicator is currently going on and off, apparently sensing conditions.

I think from what you described as well as ksoze, my system is acting similar to yours.

Thanks. The windshield and the cameras are as clean as can be. The windshield has not been replaced under my ownership and is in good shape. I have not received any check control messages, just the faults discovered by my coder on the screen shots I posted.

What do you make of those faults? He cleared them. I was thinking they could have been normal environmental faults. Do they indicate something more to you? Could they just be registered because of, for example, fog?
