I’m out of ideas. I have completed a face lift of my 2013 SL550 except for the head lights. I have all new modules and have installed the harness that was recommended. I have tried everything with my SDS but no luck. Had a computer wiz try with his laptop and struck out. I really need some help. The response before from some members was “a lot of coding”. I need some detailed information to pull this off. Please give me some ideas, I’m really tired of the sunset curfew I now have. I would appreciate any help to finish this project
Thank you

 

Was the "computer wiz with his laptop" benzninja?

 

No it wasn’t, we have someone that does magic for our shop with his computer. He tried very hard but no success. I can reach out to Benz ninja.

 

What's your "sunset curfew"?

 

I think he is saying that he can't drive the car at night because his lights do not work??

 

Yes have to be back before dark.
no head lights.

 

Do you have your “old” headlights or another type you can install?

 

I can’t install the old ones they physically don’t fit the new nose.

 

sorry. Not familiar with the upgrade. Are the lights genuine Mercedes or aftermarket? Back in the day, I put aftermarket LED bulbs in my 2004 SL500. The headlights worked, but when I put LED lights in the fog lamps, they didn't and I had to go back to halogen.

 

These are OE Mercedes head lights and modules
There are 3 modules in each head light assembly

 

did you ever get it figured out, i want to do the same facelift but dont know what harness to buy, and would like some help, im willing to pay as well i have a 2013 sl550
