OK I determined why I was getting the error from NCS Expert...I was setting the line
"WL_SL_1" as "aktiv" when it should have been "soft_einschalten" - this fixed the error.
This did not, however, cause my Angel Eyes to come on when I unlock the car. The rear Daytime Running Lights from the taillight are also not coming on.
To do the "Corner Delete Mod" I changed the value of "SIDEMARKER_US" to "nicht_aktiv" - again, the corners are now off when the headlights are on but my Angel Eyes do not work for the Welcome Light.
Does anyone have any ideas what my problem may be?
