Hello everyone, I'm sorry in advance if I didn't manage to find an answer in the other posts. during my installation of interior mood lights, a box supplied with it does the coding on its own. However, my cup holder LEDs went out. Does anyone know which coding line is linked to the cup holder, the famous Leuchte. I think I must have 1 at 0% illumination. thanks in advance

jorginho : Hi. I acknowledge that it's no solace - but yet again, this is another example of the dangers of using One-Click-Apps (OCAs)!! They may be marketed as easy to implement and cheap - but anyone that uses OCAs is rolling the proverbial dice!! Sometimes they win and sometimes they lose!!
And extending the gambling analogy: the more times that the dice is rolled - the greater is the probability of a failure that is very difficult to unwind because the coding changes made to the car are kept secret!!
OK - rant over!!
I have NEVER used OCA's - but I'm not surprised that this particular OCA has gone pear-shape on an Audi A3 8V! This is because any time the wiring diagram for a component on a VAG vehicle contains an asterisk, the greater is the chance that a OCA will cause problems.
To explain, an asterisk in the wiring diagram means that the electrical connections in a car are altered depending on build year, or other equipment options that may have been installed. Such is the case for the wiring for the cup holder on an Audi A3 8V
According to the wiring diagram, the power-supply for the cup-holder changes depending on the following: - For models with LED headlights
- From May 2016
- For models with xenon headlights
- For models with halogen headlights
- For models with additional lights
This means that for the OCA to correctly implement this tweak, it would need to successfully test for EACH (and ALL) the conditions above - how does a OCA test for "models with additional lights"?
So, because the wiring diagram for cup holder contains many asterisks - I suspect that the OCA has incorrectly assumed the wrong power-supply for the tweak. And again, because there are multiple asterisks on this component - unwinding the changes made by the OCA is complicated!

Hello dv52 (Australia), thank you very much for your quick feedback. Unfortunately the coding of the ambient lights has not been done with the Oneclick applications. It's an external box, linked to the installed led. Normally, I have rings to replace the original ones for the cup Holder but I didn't want to, as I prefer to keep them in white. In my situation it's a 2019 Audi A3, LED headlight, not Matrix. This little electronic box for managing the LEDs (because the colors can be changed directly via the MMI) must have cut off the cup Holder part, or lowered the brightness to 100%. I've had a look at the adaptations, but I can't find anything to do with the cup Holder. Thank you very much Don

OK - that's not as I understood your problem!
It's almost impossible to say with any confidence how this non-OEM "external box" works - but as a general comment, not ALL LEDs are created equal!
Simply because both the factory cup holder and the non-OEM "rings" are LED based doesn't mean that the factory LED will operate with the "external box".
Again, I know nothing about the design of the non-OEM "external box" - but the characteristics of the color-changing power-supply that drives the manufacturer's "rings" will be very different to the Audi power-supply for the cup-holder LED (which is a simple PWM voltage).
If this was my car, I would unplug the factory cup-holder LEDs from the "external box" and temporarily connect the non-OEM "rings". Do the "rings" illuminate? If not, grab a multi-meter and check at which point in the cup-holder circuit the voltage is missing
