Servomotor for air recirculation flap -V113- removing and fitting - Vehicles without dynamic pressure flap servomotor -V71-
Removing
–  Remove the glove compartment: → Bodywork - Interior fitting work; Rep. Gr.68
   
–  Unscrew bolts -B-.
–  Release the servomotor -A- from its housing -D-
–  Release the pivot -E- of the servomotor from the cam disk housing -F-
–  Mark the connector -C- (to avoid confusion, if several connections are removed at the same time) and unplug it.
–  Remove the servomotor -A-.
Fitting
  A87-10282
–  Test operation of the air recirculation flap -C- and the dynamic pressure flap (fresh air flap) -B- by turning the cam disk -A-; take into account the correct fitting of the lever pivot in the slots of the cam disk -A-.
–  Position the cam disk -A- so that the servomotor fastening element can be fitted.
  Note
Vehicles without dynamic pressure flap servomotor -V71- have the air recirculation flap and the dynamic pressure flap (fresh air flap) operated by the air recirculation flap servomotor -V113- via the cam disk. To shorten the time required to reach the air circulation mode as much as possible, the cam disk has been designed so that the air recirculation flap is open and the dynamic pressure flap is closed at both extremes of the servomotor position. In fresh air intake mode (recirculation flap closed and dynamic pressure flap open), the servomotor for the air recirculation flap -V113- is roughly at the mid-point.
  A87-10283
–  Plug connector -C- into the servomotor -A-.
–  Lay the cable harness to the connector -C- so that it cannot make contact with any moving parts (eg. the levers in the intake cavity).
–  Insert the pivot -E- of the servomotor into the cam disk housing -F-
  Note
t  The pivot of the servomotor shaft -E- must only be fitted in a position where it can be inserted into the cam disk -F- without using force. If the pivot -E- can only be inserted with pressure, check the motor shaft (it may be turned 270° and applied to the other limit).
t  If the servomotor shaft pivot -E- is not in a position where it can be inserted, connect the servomotor to the vehicle cable harness. Connect the ignition and select the Climatronic control unit -J255- on the control and indication panel, on a setting where the servomotor will be in a central position (eg. fresh air intake mode) Wait until the servomotor has reached the required position then disconnect the ignition.
t  If the servomotor shaft pivot -E- is not in a position for insertion, contact “5” and “6” of the removed servomotor can be connected to a 12 V battery (with a 5A fuse) using a cable adapter (or an auxiliary cable of the auxiliary measurement set -V.A.G 1594/C-). Allow the servomotor to turn until the shaft is in a position where it can be inserted freely (roughly in mid-position); the turning direction can be reversed by exchanging the positive and negative poles.
–  Fit the servomotor -A- in its housing -D-
–  Fit bolts -B-.
Re-install all parts removed in reverse order, paying attention to the following:
–  Consult the fault memory of the control and indication panel Climatronic control unit -J255- and erase the faults that appear. → Measurement, information and diagnosis of vehicles system VAS 5051 in "Guided fault finding" function.
–  Carry out the basic setting and diagnostic of the air conditioning actuators the consult the fault memory once again. → Measurement, information and diagnosis of vehicles system VAS 5051 in "Guided fault finding" function.
  Note
In case of complaints of humidity in the passenger compartment, check also the operation of the air recirculation trap to see if it closes fully.
