BOSCH HDI EDC 15C2 INJECTION SYSTEM AND PARTICLE FILTER
100
IX - ADDITIONAL HEATING
As the engine is highly efficient, a system is required to assist the rise in temperature
in the passenger compartment in cold climates.
The passenger compartment temperature rise assistance system is controlled by the
built-in systems interface and operated by the injection ECU.
2 devices are used depending on the marketing country:
• several thermoplungers (electrical resistors) located in the coolant circuit of the
heater matrix,
• an additional fuel powered heater located in the front left hand wheel arch (for
vehicles in very cold countries).
