Good morning, For the past couple of weeks, I've been getting the run around on whether the issue I'm having with my vehicle is an active recall. I recently took my vehicle to Eurocode Tuning (Torrance, CA), and the mechanic instructed me to take my vehicle to the dealer because the issue I am currently experiencing (fuel leak in the injection system) is listed as a recall. I contacted the Audi dealership in Long Beach CA via phone at (562)610-4000, the service representative stated that he found no active recall on my vehicle. Once again contacted Eurocode Tuning and they stated to have them run a diagnostic on the vehicle and they will see its the fuel leak in the injection system. And they are required by law to fix the recall. The following morning I took my vehicle into McKenna Audi ( Norwalk, CA) and one of the service representatives reiterates that my vehicle has no active recall. I stated that I was well aware of that, however, the issue I was having was listed as a recall on the web and I was informed by the repair shop as well. I proceeded to show him the information I got offline and my failed smog that was done on my vehicle. He proceeded to show me the breakdown on his computer that it was no active recall and the only thing that they were looking into was issues regarding the turbo. He stated what I was talking about was an extended warranty and my vehicle is well past that warrant. He then proceeded to say if a diagnostic is done on my vehicle I will be responsible to pay it and any repair done on my vehicle. So I walked out and decided to contact you. I am just trying to determine whether my vehicle could be repaired under the recall. I'm extremely frustrated and concerned for my safety because the recall did state the risk of a fire. Sincerely a confused, frustrated Audi owner [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I was driving my vehicle & noticed a fuel smell. When I got to my destination shortly down the road (~1 mile) I inspected my engine for the source of the smell & found fuel leaking down the front of my engine from under the supercharger. After disassembling the top of the engine I found the injector supports to be the old recalled parts (verified with engraved part numbers). I then called the audi dealer that supposedly performed the recall and explained the situation. They were very dismissive & advised me to bring the vehicle in. After a few days (4-7) they advised me they would be having a representative from audi come look at it. I attempted to contact audi multiple times for a loaner vehicle with no response. After multiple days of reaching out, I showed up to the dealer & was given a loaner vehicle due to the kindness of another advisor. The recall: 24ap fuel injection system leak. In the audi notification to the federal safety agency they specifically call out the injector support being revised under "description of remedy" stating " implementation of reinforced fuel rail retaining bracket" & received an updated part number which changed from 06d133036h to 06d133036k. I am worried more people could have this potentially fatal issue due to the lack of craftsmanship shown at that dealer. The issue could be swiftly covered up if the customer does not have the mechanical inclination to verify correct work is being performed on their vehicle.
