Question for you: Do you have a late 2017 model or 2015-mid 2017?

Powering up the tails with the wire size of leuchte 27nsl is not overloading the circuit?

 

[ZERO815]

My understanding is you power up the Control Modules of each tail light.

I understand that also,what I meant is are you using leuchte 27 to power up all 4 tails?

 

[ZERO815]

Yes I do.

Powering up 4 lights on one 0.5mm wire shows how small the amperage requirements are.

Today I noticed a little blemish with the wiring #4713 I published a couple of days ago. I used Leuchte21 for Parking lights, unfortunately every time you hit the brakes w/o Parking lights on they flicker like a quick wink. If you code the Parking lights also as Day Time Running lights it doesn’t matter.

I came up with a slightly different solution #4715 and use Leuchte21 now to power the LCM modules. I double checked the results and couldn’t find any issues.

You cannot use channel 20 or 21 for anything dealing with light unless they are brake lights. As you found out, they will always try to be brake lights, regardless of the settings. Also, look into channel 35 (later BCMs) as I believe this is a virtual channel for controlling the tail light’s dynamic enable.

I still dont’t have a channel map from a facelift car with factory dynanic tail lights to confrim a bunch of settings but I am on the lookout for one.

The factory uses C6 channel to power up the modules adapted klemme 30G.

You got PNs for those 2 and 3 pin connectors?

Indeed it is C6 (running factory wiring setup) and using terminal 15 for powering the dynamic signal but late 2017+ uses the same wiring BUT has an official way to power it which is what I am talking about.

I use Nano MQS:

Do you consider late 2017+ facelift models?

No. 2018+ are facelift (unless in the RoW) but late 2017 models seem to have the newer facelift BCM.
