Air Bag On-off Switch problems of the 2001 Audi A4

All airbags failed to deploy in a driver's side "t-bone" collision. A-4 is equipped with side airbags. A-4 was stationary and occupied, minivan crashed into driver's door and part of front quarter panel. Van's rate of travel was 20 to 30 mph. . . . In reverse!!!. My wife suffered neck and shoulder injuries. Local Audi dealer replaced the side airbag # 8d0 880 241 aa and the airbag controller module # 8d0 959 655 g. Only at my insistance, was this work performed when I continued to question why no airbags deployed. My direct questions were met with, "you know, more injuries occur when an airbag goes off, so, your wife is probably luckier that they didn't work". Wtf?!?!?! hey buddy, let's put you in the driver's seat and ram minivan into it with the same speed and mass! also, rest your arm on the open window and see if you don't lose arm like my wife almost did. What are these guy's trying to cover up for Audi?!?!?! has there been a corporate decree of total liability avoidance with deceit being pushed down to the dealer level, or are they just idiots? I'm also in the class action regarding the oil sludge lawsuit. Now they are denying 1/2 of my claim because they say I'm missing proof of a single oil change that should be in the records of the dealership's that performed the work, which for some reason all the records pertaining to that critical timeline have been wiped off Audi's corporate comupter system. When will it all end???? I'm about to drive this m-f-ing car over a cliff! any Audi execs wanna go for a ride? I feel I've been taken for a long enough ride after some $15,000 to $20,000 in repairs over the last 6 years. Let's hope our airbags will be free of failure in the event of a future accident. Someone else's experience has been that switching out the module with the same model module has not eliminated the problem completely and it has re-occured, I. E. , red light in dash coming on again and failure to deploy bags in a crash.
