  As a running change in MY 2010, gasoline engines that can run on bioethanol (Flex Fuel vehicles) were introduced, which currently have an Auxiliary Heater Heating Element -Z35-. Refer to Auxiliary Heater Heating Element -Z35-, CHECKING .

  Currently an Auxiliary Heater Heating Element -Z35- is also installed on vehicles with a high voltage system (hybrid vehicles) and a gasoline engine. Refer to Auxiliary Heater Heating Element -Z35-, CHECKING .

  For vehicles with a gasoline engine, the electric auxiliary heater (the Auxiliary Heater Heating Element -Z35-) is activated by the Climatronic Control Module -J255- display and control head via the local Data Bus (activated via the same outlet and also via the Fresh Air Blower Control Module -J126-) on the Auxiliary Air Heater Control Module -J604-. Also check the Auxiliary Air Heater Control Module -J604- if there is a concern about the Fresh Air Blower Control Module -J126- or the Fresh Air Blower -V2- for these vehicles. Use the Vehicle Diagnostic Tester in the "Guided Fault Finding  " function and refer to the appropriate SYSTEM WIRING DIAGRAM.
