Mini Countryman Active Hood Fault and Airbag Warning
Summary of the thread
A 2017 Mini Countryman displayed an 'Active hood fault' and an airbag warning, with errors indicating triggered spring actuators. The issue was suspected to be related to the acceleration sensor, affecting the car's safety systems, particularly the pedestrian safety feature. The recommended solution was to have a professional workshop diagnose and replace the faulty sensor, which resolved the problem and restored the vehicle's safety functions.

Active hood lifters, yeah, it does. The error message specifically says 'Active hood fault' and the spring actuators were triggered. So, what exactly did you do with your Volvo? Did you fix it yourself, or did you have to take it somewhere? Was it expensive?

Yep, sounds like the same kind of issue. With the Volvo, the sensor was sending bogus signals, which messed with the whole system. I wouldn't mess with the hood lifters yourself, especially since the actuators have already fired. Best bet is to get it to a workshop. They'll diagnose the sensor and replace it. It's linked to the pedestrian safety system, so it's best to get it sorted ASAP.

Just wanted to give you an update. Took the Countryman to the shop, and you were spot on! It was the acceleration sensor. All fixed now, and the error is gone. Cost me 315€, but at least my car safety is back to normal. Thanks a bunch for your help!

Whoa, that sounds like a tricky one! I had something similar happen with my old Volvo. Airbag light, weird errors popping up... turned out to be a faulty sensor related to the collision detection system. Does your Mini have those active hood lifters for pedestrian safety? Could be related to that too.
