First of all sorry if this is posted in the wrong place as i am new to the site! i finally got my dream of owning my first BMW just before Christmas . i brought a 328i SE 4 door on a 99. Only to 4 days later have to unavoidably drive through a hole in the road caused by the recent terrible weather. the hole in question was 47" long 16" wide and 5" deep. I was travelling at 40mph and the force of this caused the N/s front, rear, and roof curtain air bags to deploy:frown. there was no structural damage to the car but i never doubted it's build that's why i chose BMW. I have found an airbag kit on eBay and blow off cable for the battery. I'm confidant i can fit all these parts but it's the ecu info that i need. Does the airbag ecu need pairing to the engine ecu? somebody told me that i would have to buy the engine ecu also! any advice would be gratefully accepted as i want to get her back to the perfect state that she deserves.
