Common Issues When Activating BMW Welcome Lights

Issue	Possible Cause	Solution
Welcome Lights do not activate	Incorrect FA coding or parameters not set	Recheck FA and ensure MAPPING_NEBELSCHW_L/R_PART_OF_WL set to Soft_On
Lights turn off too quickly or do not follow timing	Vehicle settings overridden by other modules	Verify timing settings in FEM_BODY and ensure no conflicts with daytime running lights (DRL) or lighting logic
Error messages in vehicle or CANbus faults	Faulty wiring, aftermarket bulbs, or incompatible hardware	Use original OEM bulbs/fog lights and ensure proper connection to the vehicle’s lighting modules
Feature only partially working	Vehicle not equipped with required hardware (fog lights, Adaptive LED, or KAFAS2 camera)	Confirm hardware prerequisites before attempting activation

Important Notes:

Only original fog lights or Adaptive LED headlights with cornering function are supported.
Always backup FA and coding data before making changes.
Using incompatible aftermarket lighting can trigger CANbus errors or prevent the Welcome Light animation from working.

Activating the BMW Welcome Light animation adds a premium, visually striking effect when approaching or unlocking your vehicle, enhancing both aesthetics and safety in low-light conditions.
