Coding
Coding is necessary in order to activate inner tail lamp blinker/reverse lamps. Outer lamps will work normally without coding.
1. Add “HELC” (without quotes) to HO-WORT of Vehicle Order.
2. VO Code REM module. No other coding is necessary.
Note: If coding does not activate inner lamps, it may be possible your M4 is on a very early I-Level (typically on early model MY15) and needs to be updated. Most have already been updated at dealer at some point of service or have compatible i-level software.
Install completed. Enjoy your new LCI Taillamps!
