Active Hood Fault

That sounds eerily familiar! I had a similar issue with my 2017 Opel Corsa. Almost identical symptoms: a persistent warning light related to the pedestrian safety system, coupled with the airbag light. It turned out to be a faulty sensor in my case as well, though not the acceleration sensor directly. Was the error code you retrieved specific to a particular sensor?

The error code doesn't explicitly name a particular sensor, but it refers to a malfunction within the active hood system. Is it possible that the location of the faulty sensor in your Opel Corsa is similar to the one in my Fiat Panda?

While I cannot guarantee the sensor locations are identical, given that my Corsa also experienced a triggered pedestrian safety system, it's quite plausible the root cause is similar. In my case, I ended up taking it to a workshop; they diagnosed it properly and replaced the defective sensor. It might be best to do the same to avoid further complications with the car electronics.

Based on your experience, I will schedule an appointment with a trusted workshop for a thorough diagnosis and repair. It appears the acceleration sensor was indeed defective, and the repair cost was 315€. Thanks again for your assistance.
