Peugeot 308 Active Hood Fault

That sounds like a pain! I've heard of active hood faults messing with other systems. When you say 'spring actuators triggered,' do you mean they actually deployed, or just the error message is showing?

By triggered, I mean the actuators indeed deployed. Could this deployment, coupled with the error messages and airbag light, all point to an acceleration sensor malfunction within the active hood system? I'm trying to ascertain if replacing that specific sensor is a logical first step.

Ouch, deployed ones are serious. It definitely sounds like the acceleration sensor is the prime suspect, especially with the airbag light on too – it's all part of the safety system. Messing with airbags is risky. I think you should take it to a workshop.

Thank you for confirming my suspicions. Following your advice, I took the car to a workshop; the acceleration sensor was indeed defective. Repair, including parts and labor, cost 315€. Everything is now functioning correctly.
