Hello, 
i have a problem with led lights calibration. Headlights are second hand Bixenon AHL complete pack with driver modules and led modules - same equipment, not retrofit. When dismantling from donor car, they worked 100% but now I have a problem with calibrating the LEDs. I programmed and coded them with autohex and after that trying to taught with ista - no success. I read vin from Left and right TMS and I see that only one module has changed VIN. I am not 100% sure that VIN change is necessary  for successful coding. I have one working driver module from original headlight and put it again on his place - headlight starts working properly. But after new try to taught in LED lights with ISTA stopped working like replacement modules. Any ideas how to solve the problem?

Thanks at advance

Its totaly doable by autohex I ve done many(used and new) and same car as yours..sometimes coding not inuf you need to program module to match the soft..after sucesful programing you will se vin changed and lights working
