Heating Version, Without A/C System

NOTE:

For these vehicles (For example the Audi A4) there are different versions of the heating and A/C system depending on the equipment. Make sure to use the correct version and pay attention to the allocation of different components.

For the display control head for the heater -A- in the service information, in the Guided Fault Finding and in the wiring diagram the same designation is used as for the A/C system Front A/C Display Control Head -E87-. Use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function and refer to the appropriate Wiring Diagram(s).
