Each time I fill the gas tank there is a strong smell of leaking gas. Not clearly identified the source but feel this is a significant safety risk.

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. I am upset because now it won't be fixed under recall because it's been so long however there was no close date on reports it shows several thousand cars never got the repair and was not notified. This is a huge safety issue that not only can start car on fire but house on fire if parked in garage. Now I am suppose to pay for the cost on something that was not put together correctly and is a safety hazzard because I was not warned about it by mail or when car was serviced and never had trouble till now and there are tons of customers you are not helping with same problem year make and model of car. If this results in death than it will become a more serious problem on your hand for not fixing a recall that has been known to be problems on several years of Audi's and not all Audi owners was reach or repairs done and now when we are finding out we are being turned away. If this was not something hazardous or life threatening that's one thing but something so dangerous that can take a life you should make sure every recall that is safety related and hazardous fix regardless of when notice if found. I am expecting the recalls for all fuel related problems on all Audi be fixed when customers call to inquire and not be turned away after we are sent to dealer to have it looked at.

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. They created the case but told me until the issue is verified by an Audi dealer they can't do anything. Doing so would come with no guarantees. I called the dealer & they said the cost of a diagnostic is $109. So I took it to the dealer for a diagnostic to validate the independent mechanic?S analysis. The dealership called today & confirmed the issue from the independent. Cost to patch is $452+tax (rather than completely replace the tank for $2500). This is the same resolution as the recall which is to epoxy the valve. They told me to expect a call from aoa as they just got off the phone with them & aoa would not be paying for the fix (which again is identical to the recall resolution). Aoa called & said the main reason for not paying was that the car has 169K miles & a secondary reason that I had stopped taking it to the Audi dealership. Why should mileage matter on a known safety issue" if my car was a 2001 with 300K miles would they not have sent the recall notice? regardless of mileage this is a known design fault that Audi has acknowledged. My 2000 has the exact same issue to a T that they are addressing with the 2001-2004 models. I believe that since Audi has acknowledged this, that it is a major safety issue & it"S exactly the same issue with the 2001-2004 models that they should pay for the repair.

Strong fuel fumes are present inside the car's cabin while driving or stationary with the engine both on and off. Upon inspection by an automotive tech, fuel is dripping from the fuel tank area on the driver's side under the rear seats. Fuel will continue to drip out until the fuel tank is at about 1/2 full. The rear seat bench was removed to gain access to part of the fuel tank and there is visible wet spots from fuel spilling out the tank. The tech found a hose that connects to a plastic valve on the fuel tank. The plastic valve is cracked and is leaking fuel. There is a recall from the manufacturer to repair this problem for the vehicles made in 2001 and newer but not 2000. The 2000 A6 is identical to the 2001 A6, why isn't a 2000 covered in this recall? please amend the recall to cover 2000 A6 cars.

Hi Audi refuses to fix this problem because my car is 2000 model, but it has 6 in the VIN as for recall requirements in recall yup guys issued, I think 2000 models should be included also as I have same problem as for recall for 2001 models also as said before have that 6 in my VIN number. Can you please guys review this problem, as 2000 models should be covered. If that model has a 6 in its designation, you might want to have a look at its valve... nipples, because the National Highway Traffic Safety Administration (NHTSA) says there is something wrong with them. Silly jokes aside, the safety organization has just released a recall notice for certain model year 2001-2004 Audi A6, 2002-2003 model year S6 and 2003 model year RS6 vehicles, all equipped with 4.2-liter V8 engines and manufactured from June 19th, 2001, until June 8th, 2004. A total of 5,992 Audi bearing the number 6 in their title are affected and will be recalled in the states over a potential problem described as the rollover valve nipple. "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, ? the official NHTSA press release reads. As a result, a fuel leak may happen according to Audi, which could eventually lead to a fire if an ignition source is nearby. It"S nice to know that the german carmakers make mistakes too - it lets us now that they are human as well. The recall is expected to begin during June 2011. To fix the problem, dealers will reinforce the nipple on the rollover valve to prevent leakage or repair the nipple crack. It's highly recommended that you leave your cracked nipples to be inspected by a professional and not do it yourself.
