Trying to program the headlight module and new headlight assembly to 2017 Mercedes E300. Low beam not turning on. During self test after programming it turns on then turns off once we hit continue. When we plug in left side to right side everything works. Also we noticed that there are PIDs for level sensors on the left headlight module but the right side has no PIDs for level sensors when we look at live data. Need help with this and thank you in advance.
