Three problems related to gasoline storage have been reported for the 1998 Audi A6. The most recently reported issues are listed below.
I purchased a used 98 Audi A6 pn 4/28/07. When I purchased the car, the only issues with the car were this gassy smell inside the car when you turn on the heat, and a smoke coming from the some pipe. My mechanic told me that the breather was cut, and it had to be replaced . After fixing the problem which I had to pay for. The check engine light went on. Could not do the inspection because of that problem. A few days later I started while driving I hear this beeping sound. The fuel needle immediately went down to empty, and back up again showing that I had half a tank of gas. I went to check it again. The mechanic could not see anything. So I decided to make an appointment with the dealer. In the mean time, I decided to fill up my gas tank. That's when I realized a gas smell coming from outside the car. Took the vehicle to another mechanic on my way home, to find out that my gas tank was leaking because there is a crack and I could not drive the car under such conditions because the car can set on fire while I am driving it.
