I have to admit I have >>>NOT<<< noticed this yet on the RS6, but wanted to see if someone has.
My nephew was driving the car recently, and when he filled up the tank, the fuel gauge dial remained at 3/4 tank.
He went to the next gas station, tried to fill up again, and it took $2 worth of gas, which in the US is a shot of whiskey's worth (aka nothing).
The gauge went up by a little bit, but not showing full tank.
He drove it around a bit, and once he got home, it finally had reached the magnetic north point as expected.
The car was not cold when he filled it up fully, since it was towards the end of a good 60+ mile run.
Anyone experienced this with their RS6, and if so, what was the problem and fix?
Anything I can do myself, or take to dealer?
Keep in mind I did the Sportec cooler setup with my nephew, so we are somewhat capable of DIY jobs.
Thanks.
