Skoda Fabia Active Hood Fault

That is an interesting issue. The active hood is part of the pedestrian protection system, and it sounds like the car thinks there has been a collision. I had a similar problem on my Volvo V70. The airbag light and error messages are concerning. The acceleration sensor is a plausible cause, as it is a crucial component of the crash detection system. Has the car been in any minor accidents or had any front-end work done recently?

No accidents, not even a scratch. But the roads around here aren't exactly smooth. Could a hard bump have triggered something? You mentioned pedestrian protection system does that mean the hood actually pops up in an accident?

A severe impact could potentially trigger the system, although it is designed to differentiate between normal road conditions and a collision. The active hood system is designed to pop the hood up slightly in a pedestrian collision to create a crumple zone. Given that the actuators have already triggered, it is likely the acceleration sensor is faulty and sending incorrect data to the car's computer. I advise having a qualified technician diagnose the system to confirm the faulty sensor before replacing any parts. This is a critical car safety feature, and you don't want to compromise the collision detection system.

The acceleration sensor was the problem. Replacing it fixed the error. It cost 315€, but the Skoda's safety system is working again. Thanks for the help.
