NavCoder 2.3.5 actually don't code LCM for E46 correctly
I had troubles coding LCM into E46, if you want install leds into "light postion" taillight, code LCM for work with lower voltage, then only one side (front right) is showed error in warning bulb because this side have lower voltage and show the light into led very low bright
If coded rear lights, then only to rear-left send more voltage and this light bright too much than rear right.
I think this codes for LCM is beta
