The 2.0l FSI engine with 4-valve technology
Design and function
2The 2.0l engine is based on the tried and tested
827/113 series.
Thanks to FSI technology (Fuel Stratified
Injection), the 2.0l petrol engine has taken on a
new dimension. FSI engines are more economic,
cleaner and more responsive than multi-point
injection engines.
They also meet today’s requirements in terms of
low consumption, environmental issues and
increased driving fun.
The Volkswagen 1.4-litre/77kW FSI engine, the
pioneer in this new generation of petrol engines,
demonstrated these advantages at the end of
2000 when it was used in the Lupo. It was then
followed by the 1.6-litre/81kW FSI and 1.4-litre/
63kW FSI in the Polo.
This self-study programme should familiarise you
with the new technical features of this engine.
The self-study programme shows the design and
function of new developments.
The contents will not be updated.
For current testing, adjustment and repair instructions,

Description of engine
Using the Volkswagen Audi platform, the 2.0-litre FSI engine appeared for the first time in the Audi A4,
longitudinally mounted with the engine code AWA. In February 2003, the 2.0l FSI engine with the code
AXW, identical with the Volkswagen version, was installed transversely in the Audi A3.
The following components have been further developed to meet the high demands fo
