Fuel Hoses Lines/piping And Fittings Problems of Audi A6

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.

Nhtsa 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 othe 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 beyong 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. Sincerely, ron prewitt 2015 s eastern lane spokane valley, wa 99212 (509) 953-4320.

Fuel leak from supply fuel line in an 1999 Audi A6 during very cold weather. When temperatures drop below 15-20 f the crimped end of the fuel supply line leaks fuel, which creates an intense fuel smell in the cabin, but only if not moving at high speeds. The fuel leaking from the hose travels towards the back of the engine and eventually drips onto the exhaust manifold creating intense smoke. Apparently the cold line intensified by super cooled gas streaming through it causes the metal part of the line to contract at a sufficient rate as to allow fuel to leak out. When the fule line warms up, the leaking stops. Dealer could not replicate the problem because the ambient temperature was 40f at the time of testing and hence refused to aknowledge the problem. Subsequently the problem re-occured and I took several close-up pictures showing the leak and the ambient temperature. I can make the pictures available upon request. This is very dangerous condition that can go undetected at high speeds (high airflow dissipitates the smell) and/or if cabin air gets recirculated.
