Four problems related to tank assembly have been reported for the 2003 Audi RS6. The most recently reported issues are listed below.
Fuel tank leak- the plastic roll over valve of the fuel tank cracks and leaks fuel. I am now on my 4th gas tank since I have owned the car new in Jan/04. The gas tank was replaced as recommended on each incident. The repair is a significant repair job due to the location of the fuel tank. My first repair was at 47k miles, second repair at 87k miles, and most recent at 132k miles.
After filing the gas tank there is gas leaking on the driver's side in front of the rear tire. Mechanic suspects the fuel tank rollover valve.
I would smell fuel whenever filled tank above 3/4th's. Had personal mechanic check it out, determined it was the roll over valve on the fuel tank. Called Audi of America, which stated vehicle was still covered under cpo warranty. Brought to Audi dealer who replaced the fuel tank and related parts.
The contact owns a 2003 Audi Rs6. The contact smells gasoline near the fuel tank, especially near the driver side tire. The smell is noticeable usually after the vehicle has been driven and parked in an enclosed space. The vehicle has not been diagnosed by a dealer or mechanic at this time. The current and failure mileages were 44,000.
