This comprehensive PDF file is the official VAG Self-Study Program (SSP 970133) covering the design, function, and electronic logic of Audi Occupant Protection Systems. Unlike a standard owner’s manual or a step-by-step repair guide, VAG Self-Study Programs are internal training materials designed by the Audi Academy to educate dealership technicians and engineering staff on the complex architecture of critical safety networks. Understanding how these interconnected passive restraint systems operate—and how they interpret data from the vehicle’s crash sensors—is absolutely essential for proper post-collision diagnosis, component replacement, and system recalibration.
This technical manual covers the following key safety engineering topics in detail:
- System Overview and Airbag Technology: A highly technical breakdown of the passive restraint systems across various Audi platforms. It details the deployment logic, pyrotechnic mechanics, and physical construction of the front airbags (including dual-stage deployments), side thorax airbags, and head curtain airbags.
- Seat Belt Systems: An in-depth look at modern seat belt technology. It explains the mechanics of standard belt retractors, force limiters, and the pyrotechnic pre-tensioners that instantly tighten the belts the moment a collision is detected.
- Crash Sensors and Control Modules: Comprehensive diagrams showing the location and operational logic of the primary airbag control module and the various impact sensors (such as front acceleration sensors and side-impact pressure sensors) strategically placed around the vehicle’s chassis.
- Safety System Integration: Detailed logic on how the occupant protection system interacts with other vehicle networks via the CAN bus. This includes functions that occur immediately following a crash, such as automatically unlocking the doors, switching on the hazard lights, and cutting the fuel pump.
Whether you are a professional VAG technician needing to understand why a specific airbag fault code is triggering, an automotive engineering student studying passive safety deployment algorithms, or an advanced diagnostician repairing a vehicle after a minor collision, this Self-Study Program is an invaluable resource.
(Note: As indicated by VAG training standards, this workbook teaches design and function and is not updated after publication. For exact diagnostic procedures, pyrotechnic safety rules, and component replacement instructions, technicians must always refer to the most current workshop literature.)
