^^ Brake lights are still halogen, but there is now one less bulb. The dealer will charge you an hour for coding, 1/2 hour if you are lucky. Any coder out there can do it in 10 minutes or less
. Its basically modifying the vehicle order to add the code for LCI tail light retrofit ( + MUEH). You have to write that to the two modules where the vehicle order is stored, the CAS and the FRM for the E70 using the fa write function
Then you need to code the module which controls the lights, which also happens to be the FRM. Based on the vehicle order, all parameters will be set for you, you don't need to any entries from the .trc file manually. You are basically reading the module, and writing back to the module using the sg coderien function
All this takes 10 minutes or less if you have coded before.
