Audi Q3: Temperature Regulator Door Motor -V68-, Removing and Installing
Note
- Only for vehicles with a manual climate control system (or
heater without Air Conditioning (A/C) system).
- The color-coded connecting elements on the actuator for the
identification has been discontinued as a running change as of
10/2013 for those connecting elements installed by the
manufacturer and delivered as a replacement part. Additionally
the connecting elements are no longer preinstalled on actuators
that are delivered as a replacement part. Refer to
→ Chapter "Actuator Information" and the Parts
Catalog.
- The actuators and the associated connecting elements differ.
In some cases, however, the differences are so small that they
are not always easy to detect at first glance. If a different
version of the actuator or a connecting element is installed
than the designated version, it usually leads to problems when
the basic setting is to be performed. Refer to
→ Chapter "Actuator Information" and the Vehicle
Diagnostic Tester in the "Guided Fault Finding" function.
Caution
Problems with the A/C system (heater) function after
installing the incorrect version of components
- Different actuator versions can only be
distinguished by their part number on the outside.
- The connecting elements are to some extent very
similar and are not always easy to detect at first
glance.
- If possible, only install an actuator if the new
component to be installed is available with the related
connecting element.
- Before installing, make sure that the actuator is
the right one and the connecting element being installed
is correctly allocated.
- If possible, only dispose of the removed components
after having checked the function of the newly installed
components.
Removing
- Note the general information. Refer to
→ Chapter "Actuator Information".
- Remove the instrument panel. Refer to
→ Body Interior; Rep. Gr.70; Instrument Panel; Instrument Panel,
Removing and Installing.
- Remove the data bus on board diagnostic interface. Refer to
→ Electrical Equipment; Rep. Gr.97; Control Modules; Data Bus On
Board Diagnostic InterfaceJ533, Removing and Installing.
- Free up the wiring harness -2-.
- Release the tab -3- and remove
the mount -1- from the pedal
assembly -arrow-.
- Remove the bolts -B-.
- Free up the wiring harness on the bracket
-A-, disengage the cable channel
and move to the side.
- Remove the bolts -D-.
- Push the heater core cover -A-
slightly to the side at top and remove the actuator
-B- from the temperature door
shaft.
- Mark the connector and the actuator.
- Disconnect the connector -C-.
- Loosen the connecting rod -F-
from the actuator operating lever -E-.
- Turn the actuator so far until the operating lever opening
and the latch on the operating lever align.
- Remove the actuator from the operating lever.
Installing
Installation is done is reverse order, observe the
following:
- Pry out the connecting element (here the operating lever
-E-) from the actuator to be
replaced (or select from the set of connecting elements) and
install in the new actuator to be installed. Refer to
→ Chapter "Actuator Information".
- Install the actuator operating lever on the connecting rod
-F-.
- The mount for the connecting rod -F-
can only be installed in one position on the operating lever
-E-.
- The mount for the connecting rod -F-
must align with the operating lever -E-
as shown in the illustration.
Note
If the mount for the connecting rod
-F- and the operating lever -E-
do not align, turn the mount in the actuator. Note the general
information. Refer to
→ Chapter "Actuator Information".
- Connect the connector.
- Attach the actuator to the air distribution housing.
- There must not be any play in the connection between the
actuator, shaft and connecting rod -F-.
- Carefully tighten the screws (tightening specification 1
Nm).
- Install the wiring harness so that it cannot come in contact
with any moving parts (for example, the lever on the actuator).
- Install the data bus on board diagnostic interface. Refer to
→ Electrical Equipment; Rep. Gr.97; Control Modules; Data Bus On
Board Diagnostic InterfaceJ533, Removing and Installing.
- Install the instrument panel. Refer to
→ Body Interior; Rep. Gr.70; Instrument Panel; Instrument Panel,
Removing and Installing.
After completing the repair work, perform the following
operations on the control head using the Vehicle Diagnostic
Tester in the "Guided Fault Finding" function:
- Check the DTC memory and delete any currently displayed
entries.
- Perform the basic setting.
- Perform output diagnostic test mode (DTM).
