Airbag related.

I recently bought a 2012 s550 mercedes with the stering wheel airbag deployed. I guess the guy had fix the front and not the stering wheel airbag. Now I bought a good airbag. My question is can I just put it in and plug the battery back up or is it gonna deploy again? Thank you in advance!

not an expert - stuff I've been told

the module that causes the airbag to fire should have stored the info about its deployment (so for research / make money purposes), its likely Merc claim the module will need to be replaced - some other stuff have capacitors in them to fire off pyrotechnics on seat belt buckles etc so they will be / maybe damaged where capacitors have gone throw a massive power surge - hence the surcharge on returning the old units and paying 250 for replacements

so you enter the world of I don't like paying out money so an eastern European guys has discovered how to reset the module and is busy taking over the world charging 150 to rested the box using hooky software they wrote, if you can find and or trust them its is a way to do stuff in an unapproved of manner

on each chassis leg (near the headlamp - reach from below) is a $50 sensor that doesn't like baby car park bumps, so a massive prang may leave you with some expensive surprises

Or go to the dealer, pay them, and let them fix it.
