“Fuel tank rollover nipple cracked and began leaking fuel on the catalytic converter. Causing a major fire risk, leaving me to have the car towed and repaired. Audi has recalled 2001 and up cars for this problem but left out my model year, even though it has the same tank.”

NHTSA complaint #10401509, filed 2011-05, 94,326 miles

“The first time this car had any problems with anything leaking was a couple days ago when we woke up in middle of the night to house and garage smelling like gas. On driver's side rear by passenger door there was a small leak looked like oil but smelled of gas and underneath car you can see wear a small crack is at in fuel system. I see many recalls for same thing for different years and complaints filed for this same problem and year. No recall notices was ever received by myself or previous two owners who was friends or it would have been fixed. …”

“Hello! Today I was at the sams club gas station to fill up my vehicle, 2000 Audi A6 with the 4.2 engine. When I finished, I went over to the driver side, where ive seen a huge amount of gas on the ground. The fuel was leaking really bad from my car. The sam's club even called the fired department and the police there too. It leaked out a lot couple gallons from my vehicle. Thanks god the gas station had a small incline so I could notice it right before I would drive away. Just thinking that I would drive away and something serious would happen it scares me. …”

NHTSA complaint #10670841, filed 2015-01, 141,590 miles

“Last month I filled up my tank & after doing so had a very strong smell of gas in the cabin. I took it to an independent mechanic & he told me that I have a broken rollover valve. To replace the tank costs $2500. This is potentially a very serious issue given leaking gas! After research I found there is a recall to reinforce the valve with epoxy. Unfortunately the recall is for 2001-2004 models & mine is a 2000. The issue on my 2000 is the exact same tank/valve. I next contacted Audi customer service to get a case # hoping they'd take responsibility. …”

NHTSA complaint #10503498, filed 2013-03, 169,000 miles

“First incident march 2006 leaky gas tank had to be replaced, cost to us $2,249.27, Audi denied responsibility. Requested Audi to report this issue to authorities. Second incident, 7/30/13 (mileage 163,016): very strong gasoline odor. The mechanic removed rear seat and found fuel staining all around the sending unit. Fuel tank must again be replaced. This will be our third tank counting the original one installed at the factory. In 2008 Audi issued safety recall circular code: 2ol8/jy revised in january 2009. My first fuel tank failure occurred 2 years before the recall. …”
