The engines
On the following pages, you will find
descriptions of the engines to be used in the new
Passat. They include specifications, torque and
performance curves, as well as details of
technical features and engine modifications.
In developing all engines, special emphasis was
put on raising fuel economy and reducing
exhaust emissions.
These engines now meet the following standards:
●
all petrol engines conform to the EU 4 exhaust
emission standard and
●
all diesel engines conform to the EU 3 exhaust
emission standard.
Engines in general
All engines have an electrical throttle control. For
more effective antitheft protection, the engine–
control unit communicates with the immobiliser
control unit via CAN databus (3rd generation
immobiliser).
If a component with a bearing on exhaust
emissions fails while the vehicle is in operation
(e.g. misfiring), the self-diagnosis fault warning
lamp begins to flash. If a component is identified
as being defective while the vehicle is in
operation, the self-diagnosis fault warning lamp
lights up continuously.
In both cases, the engine must be inspected
immediately.
A self-diagnosis fault warning lamp is now
integrated in the dash panel insert in all petrol-
engined vehicles.
