5 Auxiliary Air Heater Heating Element (Z35) (with Auxiliary Air Heater Control Module (J604) )
• Only on diesel vehicles. Refer to Vehicle diagnosis, testing and information system (VAS5051B) in "Guided Fault Finding" function.
• The electric auxiliary air heater is available in different versions. On vehicles equipped with a diesel engine built through November 2006 (running change) the control of the auxiliary air heater heating element is via the auxiliary air heater control module. Check using Vehicle diagnosis, testing and information system (VAS5051B) in "Guided Fault Finding" function. On diesel vehicles built from November 2006 (running change) have a 3-stage Auxiliary Air Heater Heating Element (Z35) which is controlled by a relay from the engine control module. Check using Vehicle diagnosis, testing and information system (VAS5051B) in "Guided Fault Finding" function.
• At this time, an Auxiliary Air Heater Heating Element (Z35) is also installed in vehicles with Diesel engine and parking heater as optional equipment. At a later point in time (not yet finalized), the Auxiliary Air Heater Heating Element (Z35) will be discontinued, then the parking heater undertakes the function of the auxiliary heater.
• Check the auxiliary air heater control module using Guided Fault Finding with the Vehicle diagnosis, testing and information system (VAS5051B) in "Guided Fault Finding" function.
• Removing and installing, refer to => [ Auxiliary Air Heater Heating Element (Z35) with Control Module (J604) ] Auxiliary Air Heater Heating Element (Z35) With Control Module (J604).
