Fitting   Note

t  The servomotor is supplied as a spare in the position of “fresh air option”, only when the cogwheel -A- is at the limit -B- may it be inserted correctly onto the cogwheel for the fresh air / air retention flap. If the servomotor was removed in any other position or moved while being extracted, it may not be refitted. t  If the servomotor cogwheel -A- is not at the limit -B-“fresh air option”, connect an adaptor cable → Chapter or an auxiliary cable from the auxiliary measurement set -VAG 1594C- to contacts 5 and 6 of the servomotor through a 5 A fuse to a 12 V battery. –  The servomotor will move to the limit in one direction; swapping the poles will make it move in the other direction. –  Turn the the servomotor on until the cogwheel -A- reaches the “fresh air option ” maximum -B- (see diagram).

–  Check, before trying to fit a new servomotor, the retention flap housing in the air inlet and the cogwheel -C- (the air retention flap is open, fresh air service). –  Switch ignition OFF. –  Connect the Servomotor for the air retention flap -V71- to the cable harness of the vehicle (note the correct allocation of the connectors).

–  Open the air recirculation flap -E-. –  Insert a hand into the air inlet opening for air recirculation and move the air retention flap -A- into the position “fresh air option” (the intake opening for the air recirculation option is closed).

–  Fit the servomotor -B- in the opposition direction to the arrow on the allotments -C- and onto the cogwheel -D-.

–  In order to move the cogwheel on the servomotor -A- onto the cogwheel of the air retention flap, the curved teeth -C- of the servomotor cogwheel must coincide with space between the teeth -D- of the cogwheel on the air retention flap shaft -B-. –  Fit the Servomotor for the air recirculation flap -V113- → Chapter. –  Lay wiring harness so that it cannot come into contact with moving components (e.g. control motor lever).

–  Fit the support -A-, taking into account that the support guide -B- is fitted correctly into the allotment in the air inlet opening -C- and that the support correctly inserts into both slots -D- and -E-. –  Test both servomotors, the support -A- must hold its position; if there is some play then eliminate it by applying some spongy material to the interior of the attachment points -F- of the support -A-   Note t  The position of the Servomotor for the air retention flap -V71- and the Servomotor for the air recirculation flap -V113- (and the corresponding flaps) are not visible when the glove compartment is fitted, for this reason, operation must be checked before fitting the glove box. t  If the two cogwheels (on the servomotor Servomotor for the air retention flap -V71- and the air retention flap) are assembled incorrectly, it will be noted that the air retention flap will not reach its limits (may be detected using the “basic setting” as a fault) or the servomotor will function incorrectly, unstable operation. –  Following fitting the servomotor, carry out a basic setting of the air conditioning and consult the fault memory of the climate control → Vehicle diagnosis, testing and information system VAS 5051. –  Switch on ignition.

–  Activate the Servomotor for the air retention flap -V71- and the Servomotor for air recirculation flap -V113- with the Climatronic control unit -J255- as described below, until the cogwheel is at its “air recirculation mode” limit (this diagram shows the air retention flap -A- at the “Fresh air mode” limit) and check the position of the air retention flap, this must be closed. –  First select the function “air recirculation” in the Climatronic control unit -J255-

The Servomotor for the air recirculation flap -V113- opens the flap -E- and the Servomotor for the air retention flap -V71- puts the air retention flap -A- in the position “air intake for the air recirculation mode”. Wait until both servomotors have reached their final position. –  Select the function “fresh air option” for example in operating mode “de-ice” (in this mode, the servomotors will always position themselves in the fresh air mode). The Servomotor for the air retention flap -V71- puts the air retention flap -A- in the position “air intake for air recirculation closed”, the Servomotor for the air recirculation flap -V113- positions the flap -E- in the position defined by the Climatronic control unit -J255-. Wait until both servomotors have reached their final position. Re-install all parts removed in reverse order, paying attention to the following:   Note t  The position of the air retention flap -A- is visible when the air recirculation flap -E- is closed through the air inlet opening in the plenum chamber (remove the plenum chamber cover).

t  For regulation of the retained air, the air inlet conduit is partially closed by the air retention flap -A- at high speed (from about 80 km/h) by the Climatronic control unit -J255- (the position of the air recirculation flap -E- is defined by the control and indication panel Climatronic control unit -J255-). t  To reduce the noise caused by the changeover from the fresh air mode to air recirculation mode or vice versa, the Fresh air turbine -V2-, due to the different air intake, the activation of the Servomotor for the air retention flap -V71- and the Servomotor for the air recirculation flap -V113- takes place as follows: t  Changing from fresh air option to recirculated air option: The air recirculation flap -E- opens first, then the fresh air flow duct closes using the air retention flap -A-. t  Changing from recirculated air option to fresh air option: The air flow duct opens first using the air retention flap -A-, next the air recirculation flap closes -E-.

t  In partial air recirculation mode, the air recirculation flap -E- and the Climatronic control unit -J255- put the air retention flap -A-into a centre position (the fresh air duct and the air recirculation collection ducts are both slightly open at the same time). In this way, better refrigeration is achieved for certain ranges of temperature and, at the same time, fresh air is taken in.
