⚠️ Audi overview
Audi sells premium gasoline SUVs and sedans in the US; 2.0L TDI models were sold through approximately 2015 before VW Group shifted US passenger diesel strategy. Audi erWin documents fuel tank draining via pump module service. Fuel contamination is excluded from warranty.

Fuel system notes
- US TDI Audis share VW Group common-rail architecture—gasoline misfuel before start is critical.
- Premium gasoline required on many turbo models—low octane is not the same as diesel misfuel.
- DEF cap is separate on TDI—do not confuse with diesel filler.

Frequently asked questions

Do not start the engine or cycle the ignition to RUN if the fuel pump may prime. Have the vehicle recovered to a USIFDA Certified Repair Facility and follow Audi service information for tank draining and fuel system inspection.
Does Audi warranty cover misfuel damage on an Audi?
No. Audi warranties exclude damage from improper or contaminated fuel. Repairs are typically customer-pay; document the OEM-prescribed remediation procedure.
Can fuel be removed from an Audi through the filler neck?
Audi documents fuel recovery via the fuel pump module access and/or tank removal using approved equipment—not filler-neck siphoning. Follow ISTA/TIS or erWin procedures for your model year.
