BMW Comfort Closing and Mirror Folding (F10/F11)
Closing all windows, sunroof, and folding mirrors in one move by holding the lock button on the key while locking the car provides great convenience. In the BMW F10/F11, this "comfort closing" feature is enabled through coding. We explain step by step how to do it with OBDThink.
What Does This Feature Do?
When you hold the lock button on the key (or use Comfort Access), the windows, panoramic roof, and exterior mirrors close/fold together.
Requirements
• OBDThink app
• OBD adapter or ENET cable
• BMW F10 / F11 (Comfort Access hardware required for door handle method)
• Ignition on, engine off
Step-by-Step Coding
The procedure is done in two modules. Note: Without the mirror parameter active in FRM, the closing function will not work.
1. Closing Function (CAS)
- 3003 FH_Master > KOMFORTSCHLIESSUNG_FB → aktiv (via key)
- 3003 FH_Master > KOMFORTSCHLIESSUNG_PA → aktiv (via Comfort Access door handle)
- Code it.
2. Mirror Folding / Activation (FRM)
- 3020 > ASP_BEIKLAPPEN_BEI_KOMFORTSCHLIESSEN → aktiv
- This parameter both enables mirror folding and is required for the above closing function to work.
- Code it.
Testing
Turn off the ignition, exit the vehicle, and hold the lock button on the key for a few seconds. You will see the windows and sunroof close and the mirrors fold.
Common Issues
- Nothing closes: The ASP_BEIKLAPPEN_BEI_KOMFORTSCHLIESSEN parameter in FRM is not active—without this parameter, the closing function will not work.
- Doesn't work via door handle: The door handle method requires Comfort Access hardware and KOMFORTSCHLIESSUNG_PA.
Warnings
Since windows, roof, and mirrors move remotely, ensure no hands, fingers, children, or pets are in the closing area (pinch hazard). All procedures are at your own risk.
Conclusion
Comfort closing is a few-minute coding that makes a real difference in daily use. With OBDThink, you can complete it in two modules and make it permanent.
Frequently Asked Questions
How do I trigger the feature?
By holding the lock button on the key (or the Comfort Access door handle) for a few seconds.
What if I want only windows to close but not mirrors to fold?
In this vehicle, the ASP_BEIKLAPPEN_BEI_KOMFORTSCHLIESSEN parameter is required for the closing function, so this parameter must be active for closing to work.
