BMW Daytime Running Light (DRL) Mode Configuration: F10/F11 Coding
You can configure which lamps illuminate for daytime running lights (DRL) and their brightness according to your preference. In the BMW F10/F11, this is done with a single parameter in the FRM module. We explain step-by-step how to do it with OBDThink.

BMW Daytime Running Light (DRL) Mode Configuration (F10/F11)
You can configure which lamps illuminate for daytime running lights (DRL) and their brightness according to your preference. In the BMW F10/F11, this is done with a single parameter in the FRM module. We explain step-by-step how to do it with OBDThink.
What Does This Feature Do?
It determines the daytime running light mode: you can select DRL to illuminate via different sources such as low beam, dedicated daytime running lights (ring/lower LED), or even disable it entirely. You can also adjust DRL brightness.
Requirements
• OBDThink app
• OBD adapter or ENET cable
• BMW F10 / F11
• Ignition on, engine off
Step-by-Step Coding (FRM)
1. Select DRL Mode
- Adjust the 3050 > DRL_MODUS parameter according to your preference. Options:
- nicht_aktiv → DRL off
- drl_l → DRL via low beam
- drl_s → via dedicated daytime running lights (US Xenon rings + lower) — factory default
- tfl_s → via dedicated daytime running lights (ECE/Europe Xenon rings + lower)
- tfl_ece → ECE comfort mode
- Code it.
2. (Optional) Brightness
- Adjust DRL brightness as a percentage with the 3050 > HELLIGKEIT_DRL parameter (e.g., wert_01__100%).
- Code it.
Verification
Turn the ignition off and on, start the vehicle, and with the headlights in the off position, verify that the daytime running lights illuminate from the source you selected.
Common Issues
- DRL not illuminating: You may have selected the wrong mode. For Europe, tfl_s or tfl_ece is typically preferred.
- Too bright/dim: Adjust brightness with HELLIGKEIT_DRL.
Warnings
Daytime running light regulations vary by country — ensure the mode you select complies with local legislation. All modifications are at your own risk.
Conclusion
DRL mode is a coding that directly affects the vehicle's daytime appearance and visibility. With OBDThink, you can easily configure your preferred mode and brightness.
Frequently Asked Questions
Which mode should I choose for Europe?
Typically tfl_s or tfl_ece, which operate via dedicated daytime running lights, is preferred.
Can I completely disable DRL?
Yes, you can disable it by setting the DRL_MODUS parameter to nicht_aktiv.
