Hi everyone. I know there are a few threads out there for the interior lighting having issues, but nothing specifically like the issue I am having. Most of the threads i've read were having to do with one of the LED sections completely dying out. The issue I am having is that only one of the sections (Small panel to the left of the steering wheel) is super faint and changes to other colors (faintly) when setting.
For example:
if I set color Blue (#34 on the settings) it becomes very weak.
If i set color pink, it sets it to red (but isn't as strong as if I were to actually set it to red, it's a weak red)
If i set the color to a lighter blue, it turns green.
Pictures for reference:
Is there a way to fix this? Has anyone experienced an issue like this before or has anyone got any information they can provide in resolving it? Anything is greatly appreciated!
Your RGB LED strip in question works but with reduced output compared to other segments, right?
This is one single tri-color chip supplied by external power + network.
-1 Inspect wiring for defective GND wiring
-2 Repair LED or replace light strip.
Here the nearby Door modules can be ruled out because other light segments are working.
+++ the BLUE LED is dead !

''This is one single tri-color chip supplied by external power + network.", being just one chip for all colors, there is no blue LED exchangeable.
The actual reference number is A 000 906 48 08 and it costs approximately 15$
Thank you @CaliBenzDriver & @trigital . I will order the original part from my local Benz shop when I get back home from my trip and see if the replacement fixes the issue.
Got the part directly from Mercedes. Need to remove the trim piece to replace the LED chip/lamp. Does anyone know how to remove the small trim piece on the left side of the wheel? Does the screen/display have to be removed in order to do so like the right side/large trim piece?
If you look up the video on Youtube on how to install Ambient lighting into a E-Class, plus the year. You will find a video showing how to remove this part. From what I know, it just pulls out but you should use a trim tool to do it so as to not break it.

That only shows how to remove the air vent, I haven't seen any videos on how to remove the trim piece, as the trim piece on the left side isn't needed to be removed in order to install the LED Lighting vent.
I will remove the instrument panel anyways to avoid an expensive replacement part if I end up breaking the trim piece.
Update: Removed the plastic housing from the LED chip. You cannot simply remove the LED chip and replace it. You have to unsoldier and resolder the new chip, or you have to cut the existing cable and or splice the existing cable with the new one. Unsure what's easier, but I will be attempting to cut the existing wires and splice in the new one.

So the replacement LED chip didn't work. I cut the wires and taped the new wires/chip and it didn't work. I checked the work I did and there was plenty of connection and twists between the existing wires and the new wires. Unsure what else could be at fault here. Anyone else have any ideas?
I was under the impression that you made a diag before any spending....there is no fuse for LED's but you can easily measure as Red is positive, Brown is Negative and the yellow/ black is Lin bus in/out both around 10V.
Also, as those are adresabile, sometimes after repair it needs to activate a Teach in routine with Xentry for the system to recount all the LED's.

I was under the impression from another thread having to do with the LED lights not working inside that a fuse would fix the issue as it did with their case. That is why I checked all of them before further troubleshooting.
As for the Xentry coding, i'll call my local Mercedes dealership and ask if that is something they'd do, or to see if that's something that might affect the LED chip, but I doubt it since the rest of them are working from what I've seen. But it's worth a go.
Went to an MB dealership and they said that it has nothing to do with programming. The tech said that it should work unless there is a bigger problem. Unsure what else there could be other than the new LED chip being faulty or a wire being chewed up by a rodent (highly unlikely) inside my dashboard. Unsure what to do at this point other than spend a few hundred dollars at an MB service center to have them check everything :/
I would have been asked about Teach In, not programming if the voltage is there
I asked about the "teach in" process and the tech said there is no such thing in regards to the interior lighting. He said if it were a headlight or something with the engine like a throttle body, there would be a teach in process.
Texted my old neighbor who works on Mercedes specifically. He said he's never had to "teach in" any LED interior lights before. I will call a different MB service shop in the morning to see if they have any info on if this is the case.
