In owners' own words
At a stoplight yesterday, the CVT transmission suddenly failed. When I pressed the accelerator, the vehicle would only very slowly lurch forward with a great deal of "Grinding" Noise.
My vehicle is an Audi A4 3.0. I originally purchased in 6/2003.
My 2003 Audi A4 cabriolet has the infamous P0706 code, which is a error code indicating the failure of the transmission control module.

On certain vehicles equipped with 1.8L turbo, 2.8L V6, or 3.0L engines, a change in the electrical motor components in the fuel pump can lead to an inoperative fuel pump and, ultimately, stoppage of fuel supply to the engine causing it to stall. If fuel flow to the engine is interrupted, the vehicle could stall without warning and thus present a potential risk of crash.
On certain vehicles produced from september 2002 - march 2003, equipped with 1.8L turbo, 2.8L V6, or 3.0L engines, a change in the electrical motor components in the fuel pump can lead to an inoperative fuel pump and, ultimately, stoppage of fuel supply to the engine causing it to stall. If fuel flow to the engine is interrupted, the vehicle could stall without warning and thus present a potential risk of crash.
On certain passenger vehicles, there is a possibility of xenon headlamp coating degradation over time. The luminous transmittance of the headlamp may decrease over a period of time. This condition could affect a driver's field of view, increasing the risk of a crash.
