Hi everyone I just run in to a problem with my 2016 Mercedes Benz c300 headlights they are not responding fully Right light only LED and indicators working. Left only Xenon working. We did a swap of modules to see if change anything but it didnt. The modules for left was purchased from Usa. I am not sure if reprogramming can solve this issue please help. I am located in Australia and one module is from USA.

headlight did get water damage that’s why I had to replace them.
