So for the last couple weeks, my 2000 a6 4.2 has been stalling on me and refuses to start for about 20 minutes after each stall. Most of the time, it will happen after stop and go driving and when i pull up and stop at a light, it will die. Before it dies, there is no rough idiling or anything! my car isnt throwing any codes and it has me, the local audi dealership, and the local indi shop baffled. So far, i have replaced the fuel pump, fuel filter and fuel pump relay. I tried looking up some threads but didnt find too much. Any help or direction to other threads is greatly appreciated. thanks
