Exclamation Check left low beam, bulb is good on w204

Hi Guys,
Before posting, I have already researched here and this thread exist but no one has really answered or found a solution for it, I changed my headlight assembly on my 2008 C300 and started getting the check left low beam, light bulb is good and headlights are brand new, I took it to a friend of mine who is an electrician and he checked the fuses and relays for about two hours and couldn't find the problem, he did find that the low beams are not getting power!! but everything else is, so he suggested me to just get new relays but was uncertain if it will fix the problem, before taking it to the dealership and get raped with the service bill, anyone have any idea what this could be? I really need help, I got pulled over twice last night since it happened, and I usually get off at 8:00 . I appreciate your help.

Is there a similar relay in the fuse box you can exchange for the low beam relay now there to see if it makes a difference?

Low Beam

Did anyone ever find a solution to this problem ? Low beam not working? Its not the bulb or headlight assembly.

Im having a similar issue; however, my interior lights and dash lights went out as well. I am looking into replacing the pre-fuse box.
Several people online said this resolved their issues.
