Active hood fault

The symptoms you describe are concerning. The active hood system is designed to protect pedestrians in the event of a collision by raising the hood to create a cushion. The simultaneous activation of the airbag warning lamp and the error code related to the active hood system strongly suggests a problem within the collision detection system itself. Have you checked the wiring and connections to the acceleration sensors? A loose or corroded connection could potentially trigger a false activation.

Thanks for the quick reply! I haven't specifically checked the wiring to the acceleration sensors yet. Where exactly are those located? Are they easy to get to, or will I need to disassemble half the front of the car?

The acceleration sensors for the active hood system are typically located behind the front bumper, often near the headlight assemblies or the radiator support. Accessing them may require removing the bumper cover, depending on the vehicle's design. Given the complexity of the system and the potential for unintended airbag deployment, I would strongly advise against attempting extensive troubleshooting yourself. A qualified technician with the appropriate diagnostic tools can pinpoint the exact cause of the malfunction and ensure the system is properly repaired and reset. This will ensure your safety and the correct operation of the pedestrian safety systems.

Okay, that makes sense. I appreciate the advice! I was hoping it would be a simple fix, but I definitely don't want to mess with the airbags. I'll take it to a workshop to get it checked out properly. It turned out it was the acceleration sensor, and the whole repair set me back 315€. Thanks again!
