The bonnet hasn’t came off the latch, you’ve triggered the pedestrian protection system which detonates the bonnet. The system will need to be replaced & reset correctly by professional bodyshop/workshop unfortunately

 

Thankyou so much for your helpful response, is there anywhere I can read more about why this happens and how this is a safety feature?

also, what parts are likely to require replacing?

 

Pedestrian protection system

The system consists of peripheral sensors in the front part of the vehicle and the airbag control unit.

I believe once operated it will need new hinges as they have a charge filled device that goes off like in air bag systems.

 

Thanks Johnny, my local garage have confirmed what both you and Steve have said.

Looking forward to seeing my invoice!

 

Yeah expensive little nap that is going to turn out to be.

 

Haha! I deserve it tbh.

I’m just grateful no-one else was involved!!!

 

It's a bit new but same colour from a breakers would be a lucky find worth a quick trawl on ebay

 

It would cost you a little I suppose
