Dipped beam failure / High beam failure

Hey guys I drive an F20 LCI equipped with LED Headlights. My old headlight broke in an accident so I replaced it with a used one. I used all the modules from the broken headlight. I have tried the old headlight and it still works properly with those modules. I am getting a high beam head-light right Failure and dipped beam right failure error. The broken headlight still works. When I diagnose on INSTA, I get a 805B15 Error - Low beam headlights: Open circuits.
The high beam works on both headlights , but the low beam does not work on the right headlight

Does this mean I have to replace the entire headlight?

You will need to see if it is module related or headlight (globe) related before you start given out money, dont make my mistake and just buy in hoping it will solve the problem. Swap the module from on the headlight that controls the low beam, high beam over to the working headlight and see if it makes the headlights low beam come on. If this do work it means something is wrong inside the "broken" headlight assembly. If the light do not come on on the working headlight (Left) then put the module from the working headlight onto the broken headlight.

This way you will know if you need to replace the headlight or the module that controls the low beam, high beam. Hope this helps.

Hi, thank you for your response. I am sure that it is not the modules. I also checked with the old one and it still works perfectly the problem is the broken lens. The headlight has an open circuit I got a second opinion.
Can these LED headlights be repaired?
