Audi Workshop Service and Repair Manuals

Note:

This control motor moves two flaps which are interlinked by way of a connecting rod in the heater (not visible from outside). In the event of temperature control complaints, the connection between the flaps can be checked after removing heat exchanger but without having to take out heater (flap can be seen through opening for visual inspection). If applicable, check operation by reaching through slot for heat exchanger into heater and moving the flaps by way of the external lever.
