Other Fuel System Tank Assembly problems of the 2003 Audi A6

Check engine light on, vehicle will not pass emissions testing. Audi determined that it was due to a fuel leak from a crack in the passenger side rear rollover valve. Vehicle had been recalled in past for similar issue (performed). Tank has 4 rollover valves, only one (front driver) included in prior recall. Initial quoted $3,300 to replace tank. Audi offered to pay for replacement tank with the exception of ~$600 (repair order attached). Repair completed on 2/23/2017, car passes state inspection. As you can see by the "staining" in the attached photo, the leak was significant dealer then calls to say that car needs to be returned to perform prior recall on the newly installed tank. Recall to be performed on only the one rollover valve (driver front) that can be accessed with out removing fuel tank. Not the valve that was leaking and necessitated the replacement. I requested that Audi perform recall on all 4 rollover valves as they installed a knowingly defective part and the risk of another crack/leak exists. Dealer says Audi refuses. I have made several calls to both dealer and Audi with no response from Audi beyond a conversation with customer service. Check engine light back on 5/08/2017. Emailed dealer on 5/11/2017 (attached pdf) with my request (again), and have received no contact from Audi. Returning car to dealer for recall on the one rollover valve on 7/12/17. Audi is putting this car back on the road with the strong potential of a fuel leak.

The contact owns a 2003 Audi A6. While the vehicle was parked, the contact noticed a puddle of fuel in the driveway. The vehicle was taken to an independent mechanic where it was diagnosed that the rollover valve had a crack, causing the fuel tank to leak. The vehicle was repaired per a recall, but the failure recurred. The vehicle was not repaired again. The manufacturer was not made aware of the failure. The recall information was not provided. The failure mileage was approximately 180,000.

I have 2003 Audi A6 quattro 4. 2 l. I had in shop for rear brakes and mechanic noted fuel leaking/dripping from front drivers side of plastic fuel tank. I did internet search and found recall campaign 11v267000 anbd many complaints regarding similar leaks. I verified manufacture date 4/3/(2002 or 2003?) from vehicle which falls in window covered by recall of units manufactured between June 19, 2001 through June 8, 2004. I contacted Audi America and eventually spoke with xxxx at 877-615-2834. She assured me that my car was either not subject to the recall or had been fixed. I told her I was the owner of the car at the time of the recall ( may 2011) and my car had not been fixed. She robotically repeated that my car had either been fixed or not part of the recall. I asked her to verify that it had been fixed and she said they have no records to show that. She said I could contact the dealer that originally sold the car. I said why would a dealer in wisconsin who sold the car in 2003 have any records regarding a recall issued in 20011 when I owned the car? she was silent. I asked for a list of all vins in the recall. She said she could not give me that. She agreed to send me a "range" of affected VIN's. She said they might be able to help me out but I need to have and evaluation done at my expense at an Audi dealer to determine what is wrong. I said I know what is wring, it is leaking gas from the rollover valve connection on the tank and reported all over the internet in Audi forums etc. I have made an appointment with Audi for 31 October min 1 hr labor at $110/hr to evaluate my leak. This recall needs to be enforced and Audi needs to be held accountable for their evasive responses.
