2013 Audi A6 NHTSA Investigations

NHTSA has opened two investigations that cover the 2013 Audi A6. One led to a recall and one other has closed.

  • Engine stalling after turbocharger failure

    Closed

    NHTSA's preliminary evaluation looked into sudden engine stalls in 2013-2016 Audi A8, S6, S7, S8 and RS7 cars with 4.0L twin-turbo engines. Owners said turbochargers failed when a clogged oil strainer cut off oil. The strainer is hard to reach for service. NHTSA and Audi had about 824 reports of these stalls. NHTSA upgraded it to an engineering analysis.

    NHTSA PE21009Opening report (PDF)Closing report (PDF)Mar 29, 2021 to May 27, 2022

  • Turbocharger failures from a clogged oil strainer

    Led to a recall

    NHTSA's engineering analysis looked into engine stalls in 2013-2016 Audi A8, S6, S7, S8 and RS7 cars with 4.0L twin-turbo engines. Audi filed recall 22V-178 to replace the oil strainer with a larger mesh one. Cars built since 2017 with that strainer had no reported turbo failures from oil starvation. NHTSA closed the analysis, citing the recall.
