Hello, I dropped my car off at Audi and Dominion in San Antonio Texas on Thursday July 10th for a repair this was a recall for the fuel pump system in something in the mechatronic controls.

The low pressure fuel pump, located in the fuel tank, shorted out and melted surrounding plastic housing. The pump is available for for inspection and has been verified by an independent service center. The vehicle and failed component have not been inspected by the manufacturer, police or insurance reps. Audi of America was contacted, but declined to inspect or pass the issue to technical representatives. There were no warning lights or messages. Symptoms included hesitation at startup.

While driving at highway speeds, a warning light appeared as well as an alert indicating the car was limited to no more than 4000rpm. After coming to a stop, a strong smell of gasoline was noticed in the passenger compartment. Continued driving home uneventfully but the strong smell of gas persisted. The next day I drove the car to a mechanic. Their inspection notes the following: The technician verified the customer concern of a fuel smell. He performed a fault scan, finding codes for low fuel pressure. He inspected the vehicle, finding a major fuel leak under the intake manifold, most likely from a cracked fuel rail. The system is supposed to operate at 125 bar of fuel pressure, but is currently at 9-11 bar. The high pressure fuel pump is operating at 100% duty cycle, which means it has overheated and been damaged. …

The car started having issues around February 2024. The car first started misfiring and dying at stops which was a safety issue. When parked I noticed that there was an excessive amount of fuel that started coming out of the charcoal canister, another problem that could have resulted in the car catching on fire. The car could not be filled up with more fuel as there was pressurized fuel coming out through the fuel filler neck when the cap was removed. The problem was determined to be related to the currently active recall. I waited for 5 months for there to be a fix for the recall without being able to use the vehicle. I finally got tired of waiting and had my mechanic repair it. The fuel tank and charcoal canister were replaced and the old parts are available for inspection by interested authorities upon request. …
