The defect
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.
The risk
An engine stall can increase the risk of a crash.
