I was driving on rout 62 with my 16 year old niece and my car felt like it went into neutral, the lights on the dash started flashing. The brake pedal felt tight but I was able to pull over without causing an accident. It keeps happening and I am afraid to drive. (especially knowing there is an open recall because my airbags may not work or worse, cause severe injury due to metal shrapnel) I also read that my car has a hidden defect that the timing chain can go at any time, causing catastrophic engine failure. I brought it to an independent Volkswagen Audi mechanic where they did a diagnostic. He told me to bring it to someplace that specializes in transmissions. I looked in my owners manual and under transmissions. It says if this happens drive it to your nearest Audi shop. I emailed Audi because I read that there were recalls and technical service bulletins about the diagnostic code p0606. I saw that there are many class action lawsuits and complaints all about the same problem with my car. I can't wait years for a class action lawsuit. I live in new england and it's getting cold. This is my only car. I bought 6 months ago, in November. I have done all the service and maintenance recommended by Audi. What ever it is that is wrong with my car, Audi has fixed other cars but not fixing mine and my car. I take excellent care of my car, inside and out. It has been serviced at every recommend milage date. Nothing has ever gone neglected. My car is completely inoperable and it is due to defects that were made during manufacturing. I do not trust Audi customer service or the Audi service center.
