This comprehensive PDF file contains the official VAG Self-Study Program 436 (SSP 436), focused entirely on the significant modifications and engineering updates applied to the popular chain-driven 4-cylinder TFSI engines. Representing the evolution of the incredibly successful EA888 engine family (bridging the gap between the initial Generation 0/1 and the highly revised Generation 2), this manual details the specific changes Volkswagen and Audi implemented to reduce internal friction, improve fuel economy, and meet increasingly stringent global emissions standards. This technical training manual is an absolute must-have for VAG technicians, engine rebuilders, and tuners who need to understand the exact differences between the various iterations of the 1.8L and 2.0L TFSI platforms.
Please note: As a supplementary Self-Study Program, this document focuses specifically on the modifications made to the baseline engine. For a complete foundational understanding of the engine block and architecture, it should be read in conjunction with SSP 384 (which covers the original development level 0).
This detailed technical training manual covers the following key engineering updates:
- Internal Engine Modifications: A deep dive into the friction-reducing changes made to the rotating assembly. It details the specific modifications to the pistons, the implementation of new, lower-tension piston rings (which has major implications for engine builders and those diagnosing oil consumption), and the updated main bearing clearances.
- The Audi Valvelift System (AVS): The most significant technological addition. The manual provides a thorough explanation of how AVS was integrated into the 2.0L TFSI variant, utilizing sliding cam pieces on the exhaust camshaft to alter valve lift, drastically reducing turbo spool time and increasing low-end torque.
- Self-Regulating Oil Pump: Essential reading for understanding engine lubrication. It details the design and function of the newly modified, map-controlled, fully variable oil pump designed to reduce parasitic drag on the engine by only providing maximum pressure when demanded by engine load.
- Engine Management and Emissions: An overview of the updated Bosch Motronic engine management system required to control the new AVS and oil pump systems, as well as the changes made to the catalytic converters to meet Euro 5 emissions standards.
Whether you are trying to understand the exact actuation of the AVS system, diagnosing an oil pressure issue related to the new regulating valve, or researching the piston ring design before an engine rebuild, SSP 436 is the definitive technical resource for the EA888 Gen 2.
