Ive been looking for a way to get around having a resistance on my LED Fog lights and somon told me it can be coded away. So i asked mercedes (closest to me) and they said they havent done it before but for 160 dollars they will give it a try. Now im not keen on paying 160 dollars pr time i have to get something coded and im not to keen on puting resistors in my car. I see BMW has a carly app on their phone that they can code with but carlys dont work for coding mercedes. Anyone have a tool that i can use to code a mercedes GLK 220 09?
