# Service bulletin Update Bulletin

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

On Audi vehicles with Concert sound system \(PR\-8UQ\) and active loudspeakers \(PR\-9VD\) manufactured within a specific period, the sound signal may be switched to mute until the next time the ignition is switched off and on again. This will occur when there is a DTC stored in the amplifier \(digital sound system control module, J525 \(address word 47\)\). This Update is in effect until removed.
