Self Study Program 465 – The 1.2L 3-cylinder TDI engine with common rail fuel injection system

VAG SSP 465. The 1.2l TDI engine with common rail injection system has joined the new generation of efficient, economic and dynamic diesel engines from Volkswagen. This new three-cylinder diesel engine was developed on the basis of the 1.6l TDI four-cylinder diesel engine introduced in early 2009 and replaces the successful 1.4l TDI engine with unit injector system.

The new 1.2l TDI engine not only meets the growing demand for dynamics and comfort in an ideal way, it also boasts extremely low consumption and pollutant emissions.

Thanks to this engine, the Polo Blue Motion scores top marks with a minimal fuel consumption of 3.3l/100km and CO2 emissions of 87g/km.
