尾部消音器，带 发动机声音系统 声音执行器 4G0071901B

The innovation with built-in aha effect.

The two actuators of the engine sound system sustainably intensify the typical engine sound of the TDI®, one actuator is integrated into each end silencer of the exhaust system. They basically work like a loudspeaker membrane in that they modulate certain sound frequency's which are specifically tuned to the driving situation. The electronic regulation is via various technology packages which connect the engine sound system to the onboard electronics. This progressive solution amplifies the typical TDI® engine sound again: an impressive and authentic sound is produced. The intensity can be controlled by the driver via the Audi drive select® driving dynamics system, if fitted. The fitting of the engine sound system does not influence the emissions values of the vehicle.
