Audi: Adaptive Light Malfunction, changed blown bulb, warning still present.

[Bolshoi]

Changed the H7 bulb on driver's side, but checked both with multimeter. Error still comes up in screen between gauges, my Motopower OBD tool doesn't see the error and can't erase it. Do I need to buy another diagnostic tool? Will MMI reset fix this? Negative terminal? I don't have a Windows laptop so VCDS isn't really an option.

OBDeleven is solid. Try that

I did, it doesn't see that error. It's not a CEL or anything on the dash, just a message on the screen.

as far as i know just replacing the bulb should fix it. does not require any clearing. very odd, are there any other lights out ?

This is B8.5?

If you have a message about a problem with the front lights, there is going to be a DTC in the J519 (09-central electrics). Does the message present at ignition on, at engine on, at headlamps on? Put the switch to off or on, not auto, when trying to sort this. Usually, the bulb errors only present when the bulb is invoked.

Message or not, does the lamp actually function?

The bulb is not driven directly by the J519. It's powered by the control module on the headlamp, which the J519 talks to via private CAN. But unlike B9 where the headlamp modules are accessible from the gateway, I do not believe the J667 / J668 modules for B8 AFS are addressable directly by gateway.

module 4 drives the HID bulb
module 5 drives the LED lights
module 6, only with AFS, drives the HID movement motors and the static cornering lamp

I believe 4 and 5 are on the bottom, 6 is on the side.

Engine or ignition on, headlights do their dance, 10-15 seconds later I get Audi: Adaptive Lights malfunction. It's the cornering lights, well, only the drivers side that blew. Both bulbs replaced, both were tested by multimeter before going in because I didn't want to take them out again. Error appears with all light modes. Bulbs do not turn on under any circumstance.

You have to clear the code with something otherwise it will constantly say the bulb is malfunctioning. Went through this a few times and just changing a bulb will not clear the code.

[Smac770]

Once this message comes up, "Audi: Adaptive Lights malfunction", there has to be a DTC in the control module. It would make no sense to have an error message and not have an error code. Should have been an 02235 it seems (which is a DFCC, not a P code, but they're all DTCs).

As mentioned, there's a few times where the code simply being present will prevent operation, and the code has to be cleared once the errant condition is amended. Or you have to do some many drive cycles before it self clears.

I don't see clearing code helps in this case.

His new bulb(s) do not turn on by his observation.

I’m telling you from first hand experience that you have to clear the code after changing the H7 cornering bulbs to make the car kick on the AFS modules again; with the code present, and as others have stated like the Audi-encyclopedia @Smac770, the code will prevent the car from enabling the AFS modules that control the on/off of the H7 bulbs.

Just adding new bulbs does nothing for the code stored in the computer.

My bad. Thanks for pointing out that part: code prevents operations.

H7 bulb… with AFS? We should be talking D3S bulbs.

That was my initial thought as well, is this misuse of the halogen term. But as it turns out, the static cornering lamp is the same H7 12V 55W halogen bulb as used for the low beam and the high beam bulbs in the halogen headlamps (ie, it's actually the same p/n). The turn signal bulb is a traditional incandescent bulb.

No problem, it’s an understandable thought that once you change the bulb the car should be intelligent enough to realize being that it can check bulb out errors. I learned this the hard way and that’s why I could make certain statements.

Yeah the AFS feature is the bi-xenon D3S lights moving left and right as the position of the nose of the car changes per the steering wheel input.

AFS headlights also give the car the cornering bulbs that are short-sightedly (IMO) halogen H7 bulbs that only turn on under specific conditions such as speeds under 15 or 20 MPH IIRC. Unfortunately rumor has it that swapping to LEDs will cause the AFS modules to burn out; I’m not sure of this but do use a Philips extreme white vision H7 halogen whatevers instead, and I’ll say the hue isn’t my favorite.

Again Smac770 is correct and for reference, below is an image of my headlights during my projector swap where you can see the halogen blue bulbs for the cornering lights. The projectors sit in a motorized bracket that are also controlled by the AFS module and move the projectors right to left.

can someone confirm: what is the proper way to clear the code using odb11 after replacing the H7 cornering bulb? thanks :)

[Smac770]

Apparently there's a trash can icon in the bottom right when looking at the faults list under a control module. Press that.

I just changed my passenger side cornering light since it was burnt, vhanged driver side too while at it, i cant clear the code too with my obd ( blue driver) , still have the "headlight range control: headlight converter active: range reduced" and right after the "audi adaptive light defective" error codes but cant clear them

Ive tried with obd2/obdeleven still when i clear the code it comes back .5 seconds later can the dealer clear that code or maybe its a wire that broke inside the headlight?

[Smac770]

If the code won't clear, then the condition triggering it is likely still present. If you have OBDeleven, do a scan, find the history log, post the history log so the complete story of the whatever is wrong can be seen (well, as much as OBDeleven can show; it's no VCDS).

It could be anything related to whatever the code is talking about. The cryptic text from the blue driver implies this is about the range control, not the lighting elements.
