What 2009 Audi A4 Cabriolet owners say
Air bags
Takata recall I waited one year for the driver's side part to come in. I lost out on driving this vehicle for entirely one year. Now there is a recall on the passenger side and I can't take any passengers until it is fixed. Mohegan lake Audi tells me that the part wont be available until September and being that this is a convertible, this is totally unacceptable. I can't take my 89 year old mother whom I am caregiver for anywhere in this car. Please help me get this done sooner. I was patient waiting an entire year for the driver's side and lost out on driving the car for one year, 2016. Please help me.
Takata recall - I received a letter in April 2016, at least 6 weeks ago, about this recall, but the part is still not available at any nj dealership to perform the repair. The Audi recall/service campaign lookup tool says that [redacted] in parsippany has the part, but [redacted] says that they do not and do not know when it will come in. I could not reach any person at the (800) number for Audi on the recall notice, [phone]; I could only leave a message which has yet to be returned. I chatted online this morning with someone at audiusa.com/contact us but there is no information as to when this part will be available; only an apology is offered. Please assist in getting the necessary part to a convenient Audi dealership. Thank you.
