Audi Q7: Instrument Panel Vent Motor -V562-, Removing and Installing
The Instrument Panel Vent Motor -V562- is only installed on a vehicle with a "Mix" or "High" A/C system.
Note
- Depending on vehicle equipment, there are different versions of the A/C system for the Audi Q7. Make sure to use the correct version and pay attention to the allocation of different components. Refer to → Chapter "A/C System Versions" and Parts Catalog.
- Currently in this vehicle, all actuators are identical in construction. During the basic setting, the actuators are assigned and adapted corresponding to the switching sequence of the wiring. If this sequence does not conform with the specification, the actuators will adapt incorrectly and the door control will be wrong. Refer to → Chapter "Main Wiring Diagram for A/C System Actuators".
- Therefore, perform the basic setting for the A/C system after installation of the adjustment motor. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
- Using the "output diagnostic test mode" and "basic setting" functions, the activation of A/C system electrical components can be tested if necessary (for example, allocation test). Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
- After installing a new actuator, check the activation via the Front A/C Display Control Head -E87- and the actuator function. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
Removing
- Move the front passenger seat as far back as possible.
