I have a 2000 Audi A6 4.2 with 110k miles. When shift in to reverse the car moves butwhen i press the gas pedal, the car does not move and it seems as if it is neutral not reverse. However, when I shift to drive it functions just fine.
Has anyone experienced this problem? If so, what did you do to correct it?

 

You might want to consider posting this at the A6 forum. I doubt anyone will see it here.
