On December 29, 2022 as I was driving my engine light came on, the fuel gauge registered empty (I had over a quarter tank of fuel at the time), and my miles till empty display in the upper left of the instrument cluster went blank. I took my Audi to my Audi dealer and their recommended repair was as follows: Fuel Tank: After removing fuel pump and level sensor we found that the secondary fuel level sensor is built into the fuel tank is faulty. Recommend replacing the tank and fuel pump with the tank. Their reason was that if the fuel tank failed it could cause a potentially hazardous situation for the driver and passengers.

Engine malfunction prevented the vehicle to engage and a significant lag. Correction of the failure has been attempted twice and a third attempt to correct malfunction is currently in progress with no movement as of yet. Gas tank has been drained and refilled and did not correct issue. Definitely not a gasoline type issue.
