Engine and engine cooling: exhaust system

Summary

This document contains information on the warranty extension for the engine exhaust flap. Audi has determined that under specific conditions, certain deficiencies affecting the engine exhaust flap on your TDI® Clean Diesel Engine vehicle could make the engine exhaust flap susceptible to degraded performance. If this happens, the Malfunction Indicator Lamp (MIL) on the instrument cluster may illuminate due to the presence of specific fault codes caused by a faulty engine exhaust flap. (The MIL is part of your on-board diagnostic system. Please refer to your owner?s manual for additional information about the MIL.) In some locales, an illuminated Malfunction Indicator Lamp could cause your vehicle to fail a smog check program, and your vehicle registration application could be denied. Audi has not identified any vehicle drivability concerns related to this issue.
