Three problems related to front air bag have been reported for the 1998 Audi A4. The most recently reported issues are listed below.
The passenger side arbag deployed unexpectedly while driving along at 40-45mph on a secondary road. There was no collision at the time and no evidence of potholes or road debris. The dealer scanned the computer and retrieved "crash data" and claimed that the airbag system worked as expected. They noted a small dent under the passenger side door column of the car which they claimed was caused by road debris and triggered the airbag system. They referred me to my insurance company. The insurance company adjuster examined the car and found no evidence of a collision - no dent or other damage that would cause the airbag to deploy. As a result, the entire airbag safety system in the car is disabled.
After running over a pothole at 30mph passenger's side door airbag deployed. Dealer said this was normal.
While drivingthe abs braking systm which is activated malfunctioned, having no braking ability, and causing a frontal impact. The driver's and passenger's airbags did deploy but not all the way. Also, seatbelt tensioner malfunctioned, which did not hold properly the occupant, and occupant sustained a broken bone. Please provide further information.
