On the 2014-2017 Audi RS7 4.0L TFSI twin-turbo V8, nHTSA recall 22V178 / Audi campaign 21H7 covers 3,305 VIN-selected, nonsequential 2014-2017 RS7 vehicles produced from July 25, 2013 through March 30, 2017. Oil and carbon deposits can block the turbocharger oil-supply strainer, starving the turbo bearings. A damaged turbine can contact its housing or the shaft can break, causing sudden loss of power or a stall and increasing crash risk. This is not a wastegate-rattle or generic intake-carbon diagnosis.

Common Symptoms

  • EPC, malfunction-indicator or oil warning lamp
  • Extended cranking or rough idle
  • Reduced engine power or sudden loss of power
  • Engine stall

How to Fix

Check the VIN for open Audi campaign 21H7 in Elsa or the NHTSA recall lookup. The authorized dealer replaces the turbocharger oil strainer, changes the engine oil and filter, and performs the campaign scan-tool turbo/boost-system check at no charge. Follow the campaign procedure for any damage found; do not buy a turbocharger, actuator or gasket kit from this card.
