Hello everyone, i have mercedes W177 A45 amg model 2020.
I have option multibeam 642 and I would like to change my current headlights with LCI headlights.

I purchased the LCI multibeam lights ref: A1779065804 and A1779065704

Here is the connection of my current headlight:


the connection of the LCI headlight

the current cable connection of my ca

There is less pin on the LCI headlight than on the headlight of my A45.

Does anyone have the diagrams of the non-LCI class A connections like mine and LCI diagrams or picture of the harness with multibeam 642 LED option.

Good evening

Did you complete this upgrade?

Any photos or instructions?

Did you already have the correct windscreen camera, and ECUs?

 

Good evening, no I did not complete this upgrade.
a person tried to code the ballast of the headlight but he cannot get the headlights to communicate with the car.
I'm missing everything like wiring diagrams and good ballast references.

 

i would like the upgrade too. got the same a45s from 2020 with multibeam

 

I saw a class A facelift at the dealership with multibeam's headlight. The VIN of this car is W1K3G1CB8RJ448575
Can anyone give me the part numbers for the lights and ballasts for this car.
I saw a car at the dealership with lights.
or tell me what software I should use to have the part references with the VIN and wiring if possible?
Regards

 

maybe its to early for the retrofit. im waiting too

 

Good evening, everything works.
No need to modify the wiring.
My mistake was purchasing the same headlight module for both headlights.
For the left headlight, you need to purchase the moduleA247002113.
For the right headlight, you need to purchase the module A2479002213.
RJ Automotive coded my car, and everything works perfectly.
Regards

 

Hello Dear Aymeric!

I saw your thread and wanted to ask you how you did that because i am planning to do the same thing with my a45s. I currently have the Multibeam Pre LCi Headlights on with cameras everything already on the car. So now i was thinking if i buy the LcI Headlights with the new modules that it will be plug and play or not. Could you like give me a hint or explain it a little to me? That would help me out a lot!

thanks in Advance!

best Regards,

Toni

 

Hello Toni,
hardware is plug and play.
No need to modify the wiring. You just need to remove your old headlights and replace them with the new ones.
However, software is not plug and play.
you need to code the car.
Both front headlights will be faulty.
I used RJ Automotive to code the car remotely.
