Air Bag Not Deploy problems of the 2003 BMW M3

My car was in a collision where the driver of car 1 was making a turn into the main street , she turned too wide and could not complete the turn and decided to back up. . She slammed into my car ,damage was left front bumper ,broken parking light, damage left front fender , xenon headlight module,(causes the left head light to turn of sometimes) and the air bag light came on , diagnosis found drivers seat belt tensioner fault ,since there was the impact on the drivers side. The driver of car 1 was cited for he incident and also for driving on a learners permit alone. State farm only covered the body repair and declined the repair of the air bag and the head light. I am concerned about the safety of any one inside this car if there was any reason for the deployment of the air bag and it did not deploy at the time. My car was in perfect condition before this accident. I would like to have my car repaired and feel safe driving.

My car was hit on the driver side resulting in the driver's door being indented 11" from it's normal position. The inside of the door was about 2 inches from the steering wheel. The side air bag did not deploy. BMW investigated the car and said that the angle on impact was from back to front which did not trigger the air bag. The body shop, the insurance adjuster and the accident investigator all said the air bag should have deployed.
