Auxiliary Heater General Information (To The Auxiliary Heater Heating Element -Z35-)
WARNING: This page is about a different variant/trim than selected.
- A parking heater installed as optional equipment does not currently operate as an auxiliary heater.
- An electric auxiliary heater is currently planned only for vehicles with a TDI engine (without high voltage system) (introduction not yet finalized for gasoline engines without high voltage system).
- An auxiliary heater without high voltage system is not currently planned for vehicles with a gasoline engine.
- The engine control module activates the electric auxiliary heater (the Auxiliary Heater Heating Element -Z35-) on vehicles with a TDI engine (without high voltage system) (the introduction and activation not yet finalized on vehicles without a high voltage system with a gasoline engine). The control modules exchange this information with one another via the Data Bus using the Vehicle Diagnostic Tester in the"Guided Fault Finding" function and refer to the appropriate Wiring Diagram(s).
- At his time on vehicles with a high voltage system the Auxiliary Heater Heating Element -Z35- is not installed, on these vehicles the High Voltage Heater (PTC) -Z115- (with High Voltage Heater (PTC) Control Module -J848-) performs this function. Refer to HIGH VOLTAGE HEATER (PTC) -Z115- GENERAL INFORMATION, (AND TO THE HIGH VOLTAGE HEATER (PTC) CONTROL MODULE -J848-) .
- The Auxiliary Heater Heating Element -Z35- -2- is installed near the heater core -1- for the heater. Refer to AUXILIARY HEATER HEATING ELEMENT -Z35-, REMOVING AND INSTALLING
.
- Check the function and the resistance value of the Auxiliary Heater Heating Element -Z35- using the :Vehicle Diagnostic Tester in the"Guided Fault Finding" function.
