Volkswagen Golf / Golf GTI / Golf Variant. Manual - part 551

Installing
Install in reverse order of removal. Note the following:

Note

♦

Check the function of the doors and linkage before installing.

♦

Check if the lever and shafts are seated correctly in the

mounts.

– Mount the actuator -2- onto the air distribution housing. When

doing this, the toothed gear -3- on the actuator must engage

into the toothed gear -1- on the temperature door lever.

• The long tooth -4- must engage into the recess -arrow- on the

operating lever.

Note

♦

If the toothed gear on the actuator and the toothed gear on the

temperature door lever do not face each other, turn the mount

in the actuator.

♦

If the bolts cannot be installed, the actuator does not sit com‐

pletely on the housing.

– Switch on the ignition, connect the affected actuator to the ve‐

hicle wiring harness and select the setting for the desired

actuator position on the display control head (for example, the

center position). Wait until the actuator reaches the desired

position and switch the ignition off.

– Install the wiring harness so that it cannot come in contact with

any moving parts (for example, the lever on the actuator).

Note

Turn the actuator so far until it has reached a favorable position

for installation. The direction of rotation can be reversed by

switching the positive and negative.

– Check the Diagnostic Trouble Code (DTC) memory and erase

any displayed entries, then perform the “basic setting”. Refer

to Vehicle Diagnostic Tester in the “Guided Fault Finding”

function.

– Check the heater and Air Conditioning (A/C) unit function.

Note

♦

Check the function of the doors and linkage before installing.

♦

Check if the lever and shafts are seated correctly in the

mounts.

– The actuator mount -1- can only be installed in one position

on the actuating arm -2-.

• The actuator mount must be opposite the actuating arm as

shown in the illustration.

Note

If the mount and the actuating arm are not opposite each other,

turn the mount in the actuator.

– Switch on the ignition, connect the affected actuator to the ve‐

hicle wiring harness and select the setting for the desired

actuator position on the display control head (for example, the

center position). Wait until the actuator reaches the desired

position and switch the ignition off.

– Mount the actuator on the air distribution housing so that the

actuating arm reaches into the mount -1- -arrow-.

• There must not be any play in the connection between the

actuator and the actuating arm.

Note

If the bolts cannot be installed, the actuator does not sit com‐

pletely on the housing.

– Install the wiring harness so that it cannot come in contact with
