How to reset BMW pedestrian protection system?

After the automatic detection is completed, the airbag light will automatically turn off, which is a normal phenomenon within 5 seconds. A depleted battery can cause the airbag light to illuminate, simply charging the battery will resolve this. The airbag system may feedback a signal indicating low pressure in a specific airbag, generating a fault code. In this case, the fault code needs to be cleared. If there are circuit malfunctions, visit a repair shop for servicing.
As a seasoned BMW driver, I'd like to share some insights about dealing with the pedestrian protection system. This system automatically raises the hood during collisions to protect pedestrians, but if it's accidentally triggered or malfunctions and needs resetting, you must first identify the root cause. The most common issues are oversensitive sensors causing false alarms or the system deploying after a collision requiring reset. Never attempt DIY fixes – since it involves safety regulations, unauthorized deactivation could be illegal or create safety hazards. I recommend driving directly to an authorized BMW dealership. Their technicians will scan error codes with diagnostic tools, then recalibrate sensors or replace the deployment module – the whole process takes about 30 minutes. For daily driving, avoid gravel roads or bumpy surfaces to minimize accidental triggers. When my system unexpectedly deployed last time, the dealership fixed it for under 1,000 RMB and checked related wiring to prevent recurrence. Remember: road safety always comes first. Never remove the system privately to cut corners, as it might lead to catastrophic consequences.
