How come you didnt install the dashboard one?
like this
Because that isn't an OEM retrofit? But for LHD cars, isn't there now a better trim piece itself that has this light strip embedded in the dashboard trim pieces.
I already did this mod and replaced the door panels with Alcantara ones with leather armrests and mine also had the RGB LEDs.
I tested them out and I was not able to get power to some of the leds due to not having the correct plug/connector for the door control module. It was way too much work so I swapped my non-RGB and wiring from my stock door panels over to the new ones. A bit of a pain but everything is back to working as is.
This is the extra plug you need on the control module.
This is the one that I had see the missing connector
Then I purchased the G4 3 SMD LEDs that were listed above, but the seller sent me the wrong ones by accident and I had to return them, that took over a month and a half being he's in the U.K and was on vacation at the time. I haven't gotten around to reordering them either.
What lightning package does your car currently have installed?
does anyone know where I can get the control module with this extra plug on it?
Hi,
Were you able to obtain any data about the signals coming from the chips? I own an S4 and am looking to upgrade the standard ambient lighting to access the RGB I understand that this is a huge project but want to take a shot at it.

The LEDs are not your typical RGB modules. They are LIN BUS modules that take a LIN BUS instruction directed to their own LIN BUS address and convert that to a specific colour and intensity. This method significantly reduces the amount of wiring needed in the car.
Hi all. I hope someone can help me with my dilema. I have an Audi A4 B9 with multi color ambient light pack including the doors, centrale console, cup holder but footwell lights front&rear is not working. When I test it, it's blinking but after this is turning off. I would like to code somehow in order to have footwell lights powered on while I am driving. Is this possible? If yes, can you tell me what I have to do for this with OBD eleven?
TLDR: Your A4 probably has the hardware fitted for the multi-colour ambient lighting, but it's not possible to illuminate the LEDs without serious work... It is however very easy to install your own LEDs! Here's some photos of my final result: https://www.dropbox.com/sh/hel6ny57u...upsDGN8Oa?dl=0
Hey everyone!
I love the interior ambient lighting in the A4, my car wasn't factory fitted with the Extended LED Interior Lighting Pack, it only has the LED Interior Lighting Pack with the white LEDs in the doors and centre console etc.
Firstly, I wondered if it was possible that Audi simply fitted all A4 with the same hardware for the LEDs and simply limiting those of us who didn't upgrade to having just white lighting. This would make sense from a manufacturing perspective as there's less variations, less hardware and fewer parts, maybe even the option to up-sell the feature after it's been factory delivered.
I was optimistic about this, since my car is fitted with Side Assist and the Exit Warning system, which illuminates the door trims in bright red if you open the door when a vehicle (or even a person running as I tested) is approaching in your blind spot. If you have this installed, you can see the bright red illumination by going to "Car" in your MMI, then navigating to "Driving assistance" and then adjusting the brightness setting under "Side Assist".
This meant that there certainly are LEDs installed in the door trims that just don't illuminate while driving, even if they're just red LEDs.
Speaking on the forums here and looking up the part numbers for the interior lighting, it quickly became apparent that the LED Interior Lighting Pack and Extended LED Interior Lighting Pack do in fact use different hardware with different part numbers.
Next, I decided to look more closely at those red LEDs for the Exit Warning system, since they produce the effect that I want. This meant removing the entire interior door trim panel.
What I discovered next was truly amusing...
It seems as though Audi fit every A4 with the RGB LEDs required for the Extended LED Interior Lighting Pack (at least, they did in my vehicle – Maybe they only do this when the LED Interior Lighting Pack or Exit warning system are fitted.).
But... they simply cut the wiring from the LED units, rendering them useless. Amazing! They spend the money installing the parts, but simply snip the wires if you didn't specify that option.
Here's a photo of the inside of the interior door trim panel: https://www.dropbox.com/s/qqu9qistof...-leds.jpg?dl=0 Red module: Exit Warning system LEDs White module: Standard LED ambient lighting (not RGB) Black module: RGB LED module installed, but with the wiring cut
I initially thought that illuminating these LEDs would simply be a matter or re-attaching some wiring and providing power to the module. It turns out however that the module also required a data signal from the car with information such as the light colour and brightness etc. These LEDs are not set up in the same way as regular SMD 5050 RGB LEDs.
Even though they were installed, there was no simple way to illuminate the factory 'fitted' RGB LEDs.
My next idea was to simply provide 12v power to the red LEDs that illuminate the door trims for the Exit Warning system. This worked immediately, but there were some issues.
Issue 1: Since the car was detecting the red LEDs being illuminated when they shouldn't be, the car treated this as a fault and disabled the Side Assist and Exit Warning systems, and showed a fault in the Virtual Cockpit.
Issue 2: These are very bright red LEDs designed to flash for no more than a few seconds. Constantly illuminating them was causing them to give off more heat that I was confortable with. I'm confident this probably would have been okay, but I didn't want to cause any damage.
Finally, I settled on an easy solution with no issues! Here's what I did...
I purchased 4x 12v G4 LED units in red. These are very easy to find online, but I took my time to find one that only had LEDs on one side, and looked like they had an LED in a similar position to the circuit inside of the RGB module from the door (picture linked above).
Don't want red lighting? Chose any colour you like! When I tested some LEDs at home, the white looked great along side the white lighting of the rest of the interior!
It was then simply a matter of attaching some wiring to the pins, and then wiring this into the same circuit powering the white LEDs inside the door trim panels.
If anyone has an Audi A4 2020 then this doesnt work... I did the same, but I think the microcontroller is reading the current for the pins. Becuase it turns off the white LED if I connect the red one to it. Anyone else have the same problem on a 2020?
But for LHD cars, isn't there now a better trim piece itself that has this light strip embedded in the dashboard trim pieces.
Is there one that works with standard white ambient lighting? The ones I see (like this) appear to require the Prestige multi-color trim as they tap into the footwell lights.
I have a 2023 A4 and want to try the OPs method to get the contour lights stay up in white. But I see in Post #97 that this method doesn't work with the face lifted model? Anyone has more info?
Also does anyone have a diagram/guide for the following section?

I have just bought a led kit I was wondering what power cables I should tap into for the door lights abs the centre lights. Not bothered to control via mmi just want to find a power source
