I had xenon headlights installed, including automatic headlight leveling.
Now, the light failure warning in the on-board computer is constantly indicating a problem.
That the low beam headlights aren't working. It's probably because the xenon bulbs draw 35 watts.
and halogen, 50 watts.
Can I have this re-encoded?
Maybe someone can help me  THANK YOU.

First, a small note...
If you're already sending inquiries via email,
Then you should also include the vehicle data.
It was not clear from your email what the subject was about.
So, getting to the actual problem... are the encodings correct?

The xenon burners are not being monitored, while the halogen burners are. This is likely the source of the error.

Exactly, and that's why I suspect the issue might be related to the coding of the vehicle's onboard computer system.
The rest should also be checked carefully.
'If there are any error codes associated with this, that would also be interesting.'

I haven't made any progress yet.
'The above setting option is not available to me.'
'That's what my friendly neighbor says.'
Is there a way to do this on an A3 (8P)?
The lamp failure monitoring in the FIS (Fault Information System).
to disable? Is there any setting option available?
via VAGcom?

Nonsense and incompetence.
Is your dealer clueless about what he's supposed to do?
The settings are available on every single 8P model.
So, either get a VAG-COM device yourself, or find someone who has one.
Okay, and if your dealer needs training on how to handle long-term contracts...

So, I was there about half an hour ago, and he also rummaged through the menu where this is listed.
Byte 00 Bit 0: Fog lights installed (option code PR-8WB).
Byte 00 Bit 1: Equipped with xenon headlights (option code PR-6X1).
Byte 00 Bit 2: Light package installed (option code PR-QQ4).
Byte 00, Bit 3: Headlight activation (unknown).
Byte 00, Bit 4: Headlight activation (unknown).
Byte 00, Bit 5: Headlight activation (unknown).
Byte 00, Bit 6: Headlight activation (unknown).
Byte 00, Bit 7: Headlight control (unknown).
Byte 01 Bit 1: Headlight cleaning system (option code PR-8X1).
Byte 01 Bit 2: Electronic fuel pump relay.
Byte 01 Bit 7: Rear wiper activation with continuous front wipers.
Byte 02 Bit 0: Rear wiper with interval function, front wipers.
Byte 02 Bit 1: Highway turn signals.
Please provide the text you would like me to translate from German to English. I will then give you only the translation, without any explanations.
'However, the line related to the xenon headlights was missing (I also saw it on the screen). The rest of the information was present, and he could click on it and change the value from ON to OFF, essentially.'
Okay, the hood is closed again, 'there's nothing I can do.' Does anyone have an idea?

The options I posted above need to be active!
We won't get anywhere like this.
Please provide me with the COMPLETE and detailed code for both the CAN gateway and the body control module (BCM).
Ideally, you should get a complete vehicle specification sheet, as it contains all the details.

So, my friend can't figure this out  .
Is there any other way to bypass the lamp failure monitoring system?

There is a distinction between the Highline and Medium versions of the control units. With a Highline version, all equipment options are available.
The following options are not available for the medium size:
- Fog lights
- Xenon headlights
- Footwell lighting.
- Adaptive Front Lighting (AFL) with light sensor in the rearview mirror.
- Headlight cleaning system
Source: http://de.openobd.org/audi/a3_8p.htm#09
As I understand it, it won't work if it has a medium-level control unit.

Okay, that's why my question is about getting a complete scan of the vehicle.

It's a highline.
Did the friendly person also confirm that?
As mentioned before, only that one line about the xenon headlights is missing.

If you can muster the courage to obtain the requested information, we can also help you.

Do you now understand why this thread was proactively locked? Because the egg is once again smarter than the chicken.
