Headlamp program please help. Mercede rip me off
I did take it to mercede dealership and they charged me $140 to look in to it but then they told me my headlight is not communicating with they scan tool. Was told I need to buy mercede control module. If that was the case then won’t I get the error on my dash?
My issue is when light come on then self test is different time for driver and passenger side. I mean active curve light are sequences different like 1 second different.

A new control module would need programming (scn coding). And if you don't have Mercedes SD-connect diagnostic scanner + online account to perform scn coding, then a Mercedes dealer or any other Euro auto repair shop can do that for you for a fee.
If you take the time and learn how to use the search function you might avoid unnecessary spending next time.
Headlights need coding because they work in conjunction with a lot of other control units&sensors in the car. No coding in your case means you lost some of the functions these headlights perform (cornering, height adjustment for xenons, IHC if fitted).

the old headlight had water inside the housing and from there my control module was damage caused the code. I don’t have the code. After this I went ahead bought the headlight and controls module got it installed. Headlight do come on but they don’t do the self test at the same time as my passenger side.

Ask the seller for a refund if coding is not possible.
Ask the SDS technician which control unit you should buy if the one you have now can not be coded.
OE manufacturer for control unit (ballast as some incorrectly call it) is Hella.
Good luck and report back when you have it fixed.
