The gas tank or components of the tank are leaking gas when more than a small amount of gas is put into the tank. Gas leaks all over the ground from the tank and the cabin fills with gas fumes. My 18 son has been driving this car and I will not allow him or anyone else to drive the car now. After reading online that many people have this same problem, I am shocked that this is not a recall when it could be potentially life threatening and that Audi wants to charge 3K to lower the tank and repair.

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.
