One problem related to gasoline storage has been reported for the 1999 Audi A4. The most recently reported issues are listed below.
Fuel gauge erratic. Fuel gauge and distance to empty computer will fluctuate between 1/4 and 3/4 while the vehicle is stopped. This occurs regardless of the level of fuel in the tank.

Inaccurate gauge caused driver to run out of fuel and resulted in loss of control of the vehicle since steering and braking are power assisted.
