2002 Audi A6: fuel leak

Filed Jan 9, 2020 · Fuel system · 145,000 miles · MD

Filled gas tank and noticed fuel leaking from top of the tank to the ground near the inside of the passenger side real wheel. Fuel stops leaking after it drops below 3/4 full. Took the car to the audi dealership thinking it was failure of the rollover/filler neck valve recall again (the federal safety agency recall #08v157000). Audi said the filler neck was dry, but there is a leak somewhere on top of fuel tank on the same side as the filler neck. They said they could not see where the leak was coming from without dropping the fuel tank from the car. Audi quoted the repair for completely replacing the fuel tank at ~$3400. A fuel tank should never leak, and this is an extreme safety concern, not only for the drivers and passengers of the car, but all others on the road. This is also a failure of an emissions component that audi needs to be responsible for since there is raw fuel leaking all over the road.

Fuel vapors and leaking fuel appears when the fuel tank is filled beyond 3/4 tank. This is unsafe for the car to be parked inside of the garage. The fumes make passengers feel ill. Audi service departments want to charge over $2500 to repair. A recall for the rollover valve has been performed; however the audi service techs say the leakage is coming from small cracks in the defective tank. Unable to have the repair done because of costs I have driven the car with less than1/2 tank of fuel for several years . The state of utah will no longer pass my vehicle inspection due to the emissions issue. My fear is the leaking fuel could be ignited by any number of sources including exhaust/heat from the vehicle. Passengers should never have to be subject to vapors inside of a vehicle. I have been to 3 different utah audi dealerships and 1 independent audi repair garage. I have also contacted audi customer relations @ 1‑800‑253‑2834. All of the audi representatives and technicians have played dumb regarding this issue; yet the issue can be found in a number of forums where others have dealt with the same issue. Audi refuses to take responsibility or even show real concern for this safety and environmental issue.

The federal safety agency campaign number: 08v157000 volkswagen is recalling 68,240 my 2001-2004 audi a6 quattro vehicles equipped with 2.7l, 2.8l, or 3.0l engines and my 2001-2005 allroad quattro vehicles equipped with 2.7l or 4.2l engines. The aging of the plastic material in the fuel tank rollover valve combined with bending stress from the aluminum ventilation line to the rollover valve nipple may lead to cracking of the nipple. If this happens, a fuel leak may result. This is the 3rd time I've made a complaint. I have a 2002 audi a6 with this problem and yet no one will listen to me. The reason is that my engine is not included in the recall. It is the 4.2 v8 in the sedan. Audi covered that engine on the allroad version and all other engines on the sedan, so my engine was the only version no covered. I personally spent $1200 attempting to fix the problem, but I'm told the leak has returned and the noticeable smell of gas is a tell-tale sign. The mechanic stated and I agree, that the engine displacement has nothing to do with the leak. All the tanks are the same and the 4.2l shouldn't be omitted from this recall. The smell and potential danger is most evident when I fill the tank beyond 3/4 full. Every time I start my car, I wonder if this will be the explosion day. Please don't wait until my car explodes to agree with me. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

There is a known issue with the aging of plastic material on audi a6 models yrs 2001-2005.the aging of the plastic material in the fuel tank rollover valve combined with bending stress from the aluminum ventilation line to the rollover valve nipple may lead to cracking of the nipple.if this happens, a fuel leak may result. This exact issue has been diagnosed by an audi mechanic on my 2002 audi a6 4.2. It is constantly leaking a fuel and if an ignition source gets near it there is going to be a vehicle fire. The recall number for this issue is 08v157000: fuel tank rollover valve modification. Although this is a known issue it only covers audi a6 modes with 2.7, 2.8, and 3.0 engines.my audi a6 has a 4.2 engine, so it is not covered by the recall, but the recall does cover the audi allroad equipped with 2.7 and 4.2 engines. I've called audi and they refuse to cover my vehicle under this recall because they have not had enough reports of it occurring with my specific engine model. I have a daughter and this poses a very dangerous threat, its expensive to repair on my own and is a known issue reported on the same vehicle I own but because I have the 4.2 model they refuse to cover it under their recall.
