Audi is taking too long to come up with a fix for the 2005 Audi A4's that have been recalled due to unsafe passenger-side airbags. Example: waukf68e75a522472 has been recalled but the listing on NHTSA says that no remedy is available. This is unsafe and unfair to customers.
Audi has taken no action to remedy the recall on may 27, 2016 for the passenger side air bag (16v382). I have contacted both my local dealership and and Audi of America and their response was to continue to wait. I also have a seat belt locking mechanism that had it's plastic covering fall off. I asked for a warranty or good will repair, but was declined due to the age of the car.
Airbag light continues to trip. First occurrence fault indicated driver side airbag upper limit exceed. Replaced driver side airbag and connectors. Car was 47 days outside 4 yr warranty with only 42k miles. 5 months later light came on again, repair accomplished again, light came on after one day. Service tech stated that they did not know if airbag would deploy in the event of a crash. Instructed to put a couple hundred miles on car. Schedule to go back to dealer this week.
