Audi Q7: Left Side Vent Motor -V299-, Removing and Installing
Left Side Vent Motor -V299-, Removing and Installing, on "Low" or "Mid" 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.
- 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.
- 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".
- After installing a new control motor, check the activation through the Front A/C Display Control Head -E87-, and the function of the actuator (correct position of the recirculation door and the back pressure/fresh air door). Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
Removing
- Move the driver seat as far back as possible.
- Turn off the ignition.
- Remove the driver side instrument panel cover. Refer to → Body Interior; Rep. Gr.68; Storage Compartments and Covers; Driver Side Instrument Panel Cover, Removing and Installing.
- Remove the left footwell vent (driver side). Refer to → Chapter "Driver Side Footwell Vent, Removing and Installing".
- Loosen the air duct above the central tube and push as far as possible to the outer side. Remove the air duct for the instrument panel vent to do this. Refer to → Chapter "Overview - Air Routing and Air Distribution in Passenger Compartment, Front".
Caution
A/C system malfunctions in the case of interchanged control motors and/or connectors. Refer to → Chapter "Main Wiring Diagram for A/C System Actuators".
- The adjustment motors and connectors are identical. If they are installed or connected incorrectly, the corresponding doors cannot be properly adapted and/or activated.
- Clearly label the actuators and connectors prior to removal to prevent incorrect installation.
- Label the connector -C- (to prevent a mix up if several connectors are disconnected at the same time).
- Remove the bolts -A-.
- Remove the actuator -B- from the door shaft -D-.
- Disconnect the connector -C-.
Installing
Install in reverse order of removal. Note the following:
Caution
If the mount -B- for the actuator -C- is turned by hand, then the electronics in the actuator can be damaged.
Note
The actuator mount does not have a stop. It turns constantly if the actuator is activated. Therefore, this should not be activated with the adjustment motor removed.
- Check the shaft -A- and the mount -B- for the actuator -C-. They must be properly aligned so that they can be joined.
- Attach the actuator mount -B- to the door shaft -A-.
Note
Check the connection between the actuator mount and the shaft; there must not be any play.
- Connect the connector -C- .
- Tighten the bolts -A-.
- Route the wiring harness to the connector -C- so that it cannot come in contact with any moving parts.
- Perform the basic setting and the output diagnostic test mode of the A/C system. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
Note
- In this vehicle, the actuators are equipped with electronics. During the basic setting, a new control motor learns its position on the heater and A/C unit and can then be activated by the Front A/C Display Control Head -E87- (currently all actuators are identical). Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
- 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".
- Check the DTC memory on the Front A/C Display Control Head -E87- and erase any displayed malfunctions. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
