What device you need for coding headlight on Benz E-series?

There are many device you can choice to do this function,and here I take the X431 device as example.

 

NOTES:
1. If still unable to work normally after the coding completed, turn ignition off, then on again in about 1 minute, and try to switch between the high beam and low beam again. It will work.
2. If only one side headlamp has been replaced, the other side works normally, first enter the normal headlamp system to read and record all codes. Then enter the abnormal headlamp system to code. Set the code same as that in normal side system.
3. If the code is set incorrectly by accident, select the correct code and reset. The code can be changed repeatedly under this function.
