# Service bulletin Customer Letter

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Audi has determined that, under specific conditions, the turbocharger could malfunction and may cause the Malfunction Indicator Lamp \(MIL\) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. 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 an IM emissions inspection, and your vehicle registration application could be denied. Please be aware that other conditions \(unrelated to the issue described in this letter\) may cause the MIL in your vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. Dealers will diagnose and replace a faulty turbocharger if necessary, at no cost to you as long as the vehicle remains within the time and mileage limits of this warranty extension.
