a faulty intake manifold 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 and/or a faulty fuel injector may cause minor misfire conditions and, in turn, cause the Malfunction Indicator Lamp (MIL) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. Please note that it is highly unlikely that your vehicle will experience an issue with both the intake manifold and/or multiple fuel injectors at the same time. In our continuing efforts to assure proper performance of Audi vehicles, your dealer will diagnose and replace a faulty intake manifold and/or a faulty fuel injector if necessary, at no cost to you as long as the vehicle remains within the time and mileage limits of this warranty extension. Please keep this letter with your Warranty booklet and deliver it to any new owner, along with the owner?s manual.
