Airbags for MK1 C3

Post by esajoda »

Asking for help, before I cause harm to myself.

The 2005 C3 1.4HDI that I purchased had its airbags deployed ( steering wheel and passenger) , I will transfer the airbags from the donor.

My question is, where are the crash sensors located if any. I have replaced the engine wiring and didn't see anything.

I'm worried that when I connect everything and start the car the airbags will deploy.

Any pointers on how to test the system?

The crash sensors are inside the actual airbag ECU. This will need to be replaced or reset.

Thanks Wheeler, so if I replace the airbag ECU behind the gear lever I should be safe?

Yes.
Even if you were to install new airbags without changing the ECU it would not deploy the airbags. you would just get airbag errors & the airbags would not deploy. once the ECU deploys the airbags it gets 'locked'
