AUDI SSP

VAG SSP 970293 – The 2019 Audi A8 Electrics and Electronics: Innovative 48-Volt MHEV Technology for Improved Fuel Efficiency. Self Study Program 970293 covers the electrics and electronics of the 2019 Audi A8, a fourth-generation brand flagship that defines the Audi brand with its new design language, innovative touch concept, and introduction of mild hybrid technology (MHEV). The MHEV technology is based on the newly developed 48-volt electrical system, which supplies the 12-volt electrical subsystem and improves the fuel efficiency of the engines.

The self-study program describes the components of the 48-volt electrical system, including the belt alternator starter (BAS) connected to the engine serpentine drive and the lithium-ion battery positioned safely under the luggage compartment floor. The program also covers the functions and tasks of the Starter Generator C29 and the installation locations and new features of the control modules for the electrical system, networking, and comfort/convenience electronics.

The 48-volt MHEV technology is particularly unobtrusive and efficient, allowing the car to coast for up to 40 seconds with the engine completely disengaged when the driver takes their foot off the accelerator at speeds between 34.1 and 99.4 mph (55 and 160 km/h). The start-stop phase begins at 13.6 mph (22 km/h) when coasting at low speed.

Self Study Program 970293 provides a detailed look at the innovative 48-volt MHEV technology and advanced electronics of the 2019 Audi A8, making it a valuable resource for technicians and enthusiasts interested in understanding the performance and capabilities of this cutting-edge technology. The program covers the components of the electrical system, the functions of the Starter Generator C29, and the installation locations and new features of the control modules, providing a comprehensive overview of the car’s electrics and electronics.

With its advanced 48-volt MHEV technology and innovative electronics, the 2019 Audi A8 offers improved fuel efficiency and a powerful driving experience. Its use of advanced technology and innovative design elements ensures a reliable and efficient car, making it a top choice for any driver seeking high performance and advanced technology in a luxury car.
