I have also read a trouble code with my Autel MaxiAp200:
"Communication with one or several color generation and coupling modules on Lin Bus 7 is faulty"

See attachments released by MBUSA they cover 2018 but you do not list your location in some markets 2017 = 2018 USA. Should be covered by warranty, you need to have someone check using Xentry (MB diagnostics).

Thanks for your prompt reply, attached Docs and your advise.
I have alreqdy called MB and they told me that my Car is not included in This Warranty-Action (I bought a car in Germany)

Could you please just tell me why you assume, that this is a problem related to the update of the software? Have you had a similar issue before?

I have same issues same car
 

Did you find a way to fix it ? If yes please do let me know how? Because I’m having the same issue on my car its e300 2017

​​​​​​​thank you so much

Yes, i fixed it!
check all the led lights (are all the lights ok?), when one is not working, that mean the circuit is not closed and the rest of the lights in this circuit will not work either.
In my case, the led lights in the space where the driver and passenger keep their legs were not connected, that couse a problem.

Quite easy thing, but tricky if you dont have a wiring diagram.

There is also probabilty that the LED is broken, but I do not know what kind of message you would find in your diagnostic device.

Wiring diagram
 

Hi. I have the same problem with the dash ambient lighting on my 2017 e220 coupe. I’ve noticed that the footwell ambient lighting isn’t working either so I presume this is exactly the same problem. Where can I get a wiring diagram as you suggest?

Hi,
i have same problem with my Mercedes E350e like your picture shows.. How you fix it ?

The initial picture on this thread precisely replicated my fault and I found it useful to show the dealer. I initially took mine to the local Mercedes dealer and they charged me £80 for an diagnostic but they couldn’t find the cause of the fault. I asked them to check the wiring in the footwell and hey presto - the wires weren’t properly connected! This was easily rectified (apparently) and the LEDs now work perfectly. They charged me £50 for the work.

Hi LP14, maybe this is stuppid question, but what is presto wires?

“Hey presto” - a figure of speech!

Mercedes w213 Ambient Light doesn't work properly
 

My Car had issue with auxiliary battery as well , i took it off , recharge it and re-install it again , the problem came as well , so can you please point out in picture where was the poorly attached wiring harness that you re-attached it well to fix that the lights partially dimmed ? i think i have the same exact issue , if you pointingout where i can attach the wiring harness well that would fix my problem i think .. waiting for your help ASAP please

Hi, sorry i don’t really know what was poorly attached cable.. because car service fixed that.. same who change battery for me. Did you disconnect any wiring harness.. there maybe some contact problem.. double check👍

Same Problem and More - brand new GLE
 

I got my 2023 GLE 3 weeks ago after a 3 month wait.

2 days ago, my dashboard (speed & rpm screen went black, not the info screen) didn’t work for a few hours. After many restarts and a couple hours it came back to normal.

Dashboard not working. From 2 days ago. See the ambient lighting “red” working.


Today, the ambient lighting partially stopped working. Only the drivers door working, the rest of the ambient lighting is not working.

Dashboard works now. Ambient lighting only works partially. Only drivers side works. See the mid console and the replay of the car doesn’t work.


I got out of the car and locked the doors thinking that a fresh entrance would fix the lights, as soon as I touched the door handle, the car unlocked and all the windows went down on their own at the same time.

I am taking the car to the dealer in the morning. Hopefully they can fix it.

Hey any updates as what happened ? This is happening to me in my 2019 e300 as well
 

hey I was wondering if you found the fix of this cause ? This same issue is happening to me but I warranty just ran out

I have the same problem. managed to solve?

Air filter in the cabin
 

I had the same problem and I started looking on the internet without realizing that I had changed the pollen filter.
What I mean is that when you change the pollen filter on the right side of the driver, the plastic that will have to be disassembled will be 2 threads
One is for the temperature sensor (the warm air that will circulate the car) and a second for the light under the feet.
When disconnected it will turn off the lighting under the feet of both front passengers and half the lighting on the driver's side (as in the presentations above)
Try to see if these 2 contacts are well put back in place, to me that was the problem and I would not have realized if I had not changed my pollen filter myself.

Excuse me if I made mistakes in expression

Ambient light wiring
 

I'm trying to give an answer here so that we don't look for another answer if this resolution of mine is beneficial to others.

It is possible that sometimes after service B or A (when replacing air filters) some "craftsmen" forget to put back the two wires Excuse me if I made mistakes in expression

excalty, the light wire did not install back after changing the air cabin filter

Glad you discovered it, might be the cause for others' ambient lighting not working after all.
