The problem I am experiencing is analogous to a recall already announced for the Audi A6: NHTSA recall no. 00V-147, VW recall no. Ur * I have a 2000 Audi S4 with 64,000 miles. I recently received my car back from a 64,000 mile service. My gas gauge had indicated I had at least a quarter tank of gas left, and my trip computer indicated I had more than 60 miles until empty. I was on the highway when the car started sputtering. At first, I didn't know what the problem was. Luckily, I was able to turn through 3 lanes of traffic with no power and get into the emergency lane. I checked my car, and there were no obvious signs of the problem. I happened to notice that my trip computer miles counter (which I reset on every fill-up), was reading higher than would be typical. It was at that point that I suspected I had run out of gas. I called aaa, requesting a gallon of gas. Indeed, this solved the problem. I was fortunate in my situation. I doubt others who also experience this problem would be as lucky. I've already heard many stories on car forums, etc. Of owners having 'close calls' because they've run out of gas when they don't expect to. This problem has been linked to the sending unit Audi uses in these models. There have been many failures, and it is all too common a problem that needs to be addressed. It is absolutely identical to the sending unit failures on the 2000 A6, so I don't understand why it wouldn't be addressed on the 2000 A4/S4 (B5 platform) or any other model that uses the same unit.
