Recall 17V508000

Engine Stalls While Driving

Recall Details

The engine's processor could misinterpret the flywheel rotation on engine startup as a knocking condition, and could adjust engine fuel and air mix ratios as a result, causing an engine stall. Dealers will reprogram the engine control unit (ECU) software free of charge to resolve the concern.

Our Quick Take

The engine could stall while driving the vehicle due to a software concern that inadvertently adjusts air and fuel ratios for engine performance. This could result in an accident.

What Should You Do?

Recall repairs on your Audi must be performed by a Audi dealership. Audi will notify known owners of affected vehicles beginning in September, 2017. If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local Audi dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with.
