A3 8P 1.6 FAULT CODES. NEW USER HELP!!

[Audream]

Hi everyone! New member here and new VCDS user!! I recently purchased a HEX V2 cable for my A3 8P 1.6 FSI, to run some scans and check if everything is OK. I'm very new to this and trying to figure it out by reading threads here and watching youtube guides. After an auto-scan, I got fault codes for 3 addresses:
Address 09: Cent. Elect. Labels:. 8P0-907-279-23-H.lbl
1 Fault Found:
01504 - Bulb for License-Plate Light (X)
012 - Electrical Fault in Circuit - Intermittent
Freeze Frame:
Fault Status: 00111100
Fault Priority: 2
Fault Frequency: 3
Reset counter: 223
Mileage: 153374 km
Time Indication: 0
Date: 2022.12.04
Time: 18:59:00

Freeze Frame:
OFF
Voltage: 11.80 V
OFF
ON
OFF
OFF
OFF
Very rarely I get a license plate light warning on my DIS and indeed I notice the one bulb doesn't work, but 8/10 times I don't get this warning and both bulbs work fine. Note: I have only one actual light bulb and the other one is a small led integrated on my reverse camera. I don't know if it's an actual error or the system just doesn't recognize this as an actual bulb.
Address 19: CAN Gateway Labels:. 1K0-907-530-V2.clb
1 Fault Found:
00469 - Infotainment Databus in Single Wire Operation
012 - Electrical Fault in Circuit
Freeze Frame:
Fault Status: 01101100
Fault Priority: 3
Fault Frequency: 1
Reset counter: 253
Mileage: 141502 km

I have placed an ebay infotaiment screen and not a genuine MMI, so I don't know if this has something to do. Also, very rarely when I turn the ignition on, the screen doesn't turn on, I can only hear the buttons beeping when I push them, then after a frew tries turning the screen on and off, it works.
Address 56: Radio
Cannot be reached
It says just that ! Radio works perfectly fine though. Again, I don't know if it has something to do with my ebay screen, because most of these screens have a power adapter cable, not sure if it also included a fakra connector.

If anyone knows anything about these faults, please reply!!
Thanks in advance.

The last 2 codes are because of the aftermarket radio. The first could be because of the led doesn't have the resistance the car expects to read from the regular bulb.

Thank for your reply. Is there any code change that I can make to clear these faults? Or can I just clear them (if it's possible) since I know the cause of them?

I don't think you can clean the codes for the radio. I have aftermarket radio on my daughter EOS and they are always there the bulb you can try checking the resistance eadd resistor if it's too far off. If it's close you might want to clean the contacts. Or simply code out the check for license plate light. The downside is that you won't get a warning when your bulb dies.

Seems weird but either both actual bulb and reverse camera LED work, or they don't and I get the check light. Can't understand why sometimes it does that and sometimes it doesn't. Maybe it's not a good idea to just clear em out. Is there any specific coding I can make without having to intervene physically to the bulbs? (like adding resistors) It's obvious it reads lower voltage for the LED one, thus the check, but is there any way to read equally or just get them always working just by making some code changes?
Thank your for your help evo.

On my A3 8P I installed LED license plate lights from 8V (or any other Audi from ~2015 onwards). They've been error free for more than 2 years now.

After further research I found out this thread https://www.audizine.com/forum/showt...bulb-error-fix that fixes the problem through adaptation on module 46. Problem is vcds doesn't accept the security code 16017, or 41067 I found on another thread. These codes are for B8 S4 but I found nothing on A3 8P. Any ideas on this??
