Hello,
I am in the same situation as you. I had a steering wheel without controls, and I replaced it with one that has controls. I coded both options 249 and 544 via e-sys, and I coded the ECU FEM, KOMBI, and ICM. However, the buttons on the new steering wheel do not light up. Could you please tell me how you managed to make them work? Did you have to add any wiring, and if so, which one?
Thank you.
