NHTSA recall 17V508000
Engine And Engine Cooling · Volkswagen Group of America, Inc.
Details
What's wrong: Volkswagen group of america, Inc. (Volkswagen) is recalling certain 2017-2018 Audi A3 Cabriolet and a3 sedan vehicles. The engine control unit (ECU) software may misinterpret the flywheel rotation on engine start-up as a "knocking" condition, and the adjusted air/fuel mixture may result in an engine stall.
Why it matters: An engine stall can increase the risk of a crash.
The fix: Audi will notify owners, and dealers will reprogram the ECU software, free of charge. The recall began September 19, 2017.
