Hello there, many common faults will cause your 2003 Audi A4 to have fumes and a smell when idling. Generally any EVAP or gasoline vapor leaks will trigger a check engine light with an EVAP leak code. In some cases the vehicle may have a gas smell before the check engine light comes on. There are many potential causes for a vapor leak with the most common being failed vapor line, failing charcoal canister, gas tank seals, vent solenoid faults, failed gas cap, or a solenoid fault. A qualified Technician such as one from YourMechanic will be able to diagnose your gas fume smell and make any repairs required to resolve the issue.
