Pneumatic suspension system Part 2 4-level air suspension in the Audi allroad quattro - Self-study programme 243 PDF

Pneumatic suspension system Part 2 4-level air suspension in the Audi allroad quattro – Self-study programme 243 PDF. The self-study programme will provide you with information on the design and functions of the different assemblies/systems.

The 4-level air suspension system in the allroad quattro is a logical development of the selflevelling system in the Audi A6.

The principles of the suspension/air suspension system and the description of those system components which are identical in the 4-level air suspension system are described in SSP 242. The contents of this self-study program are supplementary to the contents of SSP 242.

The self-study programme is not intended as a workshop manual.
For maintenance and repairs please refer to the current technical literature.
