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-Psoftware program and connectBWM ICOM A2+B+C diagnostic system

2). Download free NCS expert software and get it work on INPA K+DCAN cable

Disclaimer:

The procedure works perfect on my E46, not sure if it works on other BMW models.

Instructions:

Open My computer

Open NCS Expert folder

Open work folder

Open a notepad "FSW-PSA.MAN” in WORK folder

Save the file

Open NCS Expert

Select File>>Load file

Select Renitor’s NCS Expert Profile

Press F1 VIN/ZCS/FA button

Copy and paste "PSW-PSW.TRC” on WORK folder to desktop

Open "PSW-PSW.TRC” notepad

Delete "nicht-”

Change "EINZEIT-DRL wert-01” to "EINZEIT-DRL wert-02”

• LSZ-11 and later remains unchanged
