Self Study Program 843103 – Passat W8 Engine Management, Motronic ME 7.1.1

VAG SSP 843103. The Motronic ME 7.1.1 engine management system used on the Passat W8 engine enables high power output with minimal fuel consumption through adaptation to all operating modes.

The heart of the Motronic system is the Motronic Engine Control Module J220. It processes incoming signals and transmits adjustment commands for controlling the subsystems.

The Motronic Engine Control Module J220 also provides information for the diagnosis of subsystems and components. For more information on the mechanical aspects of the W8 engine, please refer to The W Engine Concept, Self-Study Program Course Number 821203.
