Best way to code out Daytime running lights

[SurgeSi]

What is the best and easiest way to code out the daytime running lights on my E46?

NCSexpert + NCSdummy, PA soft, or other subscription model ones like iCarly, bimmercode

Here's a quick rundown of how to use NCSexpert & NCSdummy from Gemini:

For Angel Eyes (Halos) as DRLs
If your car has factory-fitted "angel eyes" or you have retrofitted them, use these parameters to make them your DRLs.

• GEDIMMT_FL_ALS_DRL: Change from nicht_aktiv (inactive) to aktiv (active). This dims the front turn signal bulbs to act as DRLs.
• GED_FL_ALS_DRL: This parameter may also be labeled this way, depending on your car's model and production date.
• DAUERFAHRLICHT_US: Change from aktiv to nicht_aktiv. On Canadian-spec cars, this disables the default DRL setting, which illuminates the main headlights.
• PO_ALS_DRL: Change from aktiv to nicht_aktiv. This disables the parking lights from being used as DRLs.

For dimmed High Beams as DRLs
This is a standard option for some E-series models where the high beams operate at a reduced intensity for DRL functionality.

• FL_DIMMUNG_ALS_DRL: Set to a specific value, usually wert_01 or wert_02. This adjusts the brightness level of the high beams when used as DRLs. The available values may vary by vehicle.

General coding process using NCS Dummy

1. Read your ALSZ module with NCS Expert.
   • Connect your coding cable (e.g., K+DCAN) to the car and your laptop.
   • Open NCS Expert, load a profile like Expertmode or FSW PSW MAN, and select your car's chassis.
   • Select the ALSZ module (Process ECU > ALSZ).
   • Choose the CODIERDATEN_LESEN job to read the module's data.
   • This generates a trace file (FSW_PSW.TRC) in your WORK folder.
2. Edit the trace file with NCS Dummy.
   • Open NCS Dummy and load your FSW_PSW.TRC file.
   • Find the DRL-related functions based on the list above. NCS Dummy translates the German coding language for easier editing.
   • Change the parameters to your desired aktiv or nicht_aktiv values.
   • Click "Export FSW_PSW" to save your changes to a new file, usually named FSW_PSW.MAN.
3. Write the new coding back to the car with NCS Expert.
   • Return to NCS Expert.
   • Select the ALSZ module again.
   • Choose the SG_CODIEREN job to write the new settings.
   • Execute the job and wait for the coding to finish.
