Since there is no detail instruction on disabling BMW Daytime Running lights, I decided to make my own document. I am driving a BMW E46 1998 year.
Software & Hardware:
1). Using NCS Expert in BMW ICOM Rheingold ISTA-D ISTA-P software program and connect BWM ICOM A2+B+C diagnostic system
2). Download free NCS expert software and get it work on INPA K+DCAN cable
3) Old E46 has 20-pin diagnostic connector, so I need extra 20-pin to 16-pin cable.
Disclaimer:
The procedure works perfect on my E46, not sure if it works on other BMW models.
