Audi Noise, Vibration, and Harshness

This Self-Study Program focuses on vehicle Noise, Vibration, and Harshness (NVH), their causes and diagnostic and service procedures to locate and correct NVH concerns.

Modern cars and trucks use a combination of systems to provide the driver with the safest, most responsive, and comfortable vehicle ever built. Today's driver has come to expect a smooth and quiet ride in all operating environments. When vehicle noise, vibration, or ride harshness exceeds the driver's expectations, it is up to the technician to correct the cause of the customer's concern.

Vehicle components are being manufactured using lighter weight metals. Lighter weight metals reduce the overall vehicle weight that reduce emissions and improve fuel economy. As technologies develop stronger and more lightweight metals this trend will continue. Lighter vehicle components do not absorb noises and vibrations as well as heavier components. This leads to an increase in NVH concerns.

Diagnosing NVH concerns has been developed into a logical and almost scientific procedure. This course will provide the Audi technician with concepts to help understand and diagnose NVH concerns.

Audi Self Study Programs are designed to help the Audi dealership technician prepare for intensive factory training classes. This book provides introductory information regarding the introduction of new features, designs, and functions.

Caution:
Audi Training Literature is not a Repair Manual. For maintenance and repair work, always refer to the current technical literature.

This technical training is based on information available at the time of its original publication and assumes that repair work will be performed in a dealership by a qualified service technician.

Audi is constantly updating its automotive systems and designs; therefore, this booklet may not cover components or systems that have changed over the course of the vehicle's production, and will not apply to vehicles produced after its publication date. It provides conceptual background for the professional automotive technician rather than specific service instructions.

Audi Service Training literature will be most useful for those seeking a better conceptual understanding of Audi's innovative design and engineering. While it is not for vehicle repair, it is more technical than most sales literature, and it provides a useful theoretical background for using repair manuals.
