Removing and installing right mounting plate with control motors V109 and V111
Removing and installing right mounting plate with control motors -V109- and -V111-
  Note
t  The mounting plate with the right footwell flap control motor -V109- and the right centre vent control motor -V111- is only fitted on vehicles with an air conditioner of the „Deluxe“ type.
t  Dismantling and assembling right mounting plate with control motors -V109- and -V111- → Chapter
t  At present all the control motors on this vehicle are identical. During basic setting, control motor assignment and adaption are implemented on the basis of the arrangement in the series connection of the wiring. If the sequence is not as specified, the matching of the control motors and thus flap control will not be correct → Chapter (block diagram of air conditioner control motors).
Removing
–  Move the front passenger's seat to the rearmost position.
–  Switch off the ignition.
–  Remove the glove compartment → General body repairs, interior; Rep. gr.68.
   
–  Remove the bolts -A-.
–  Unfasten the air duct to the dash panel vent from the dash panel cross member on the right (do not remove) → General body repairs, interior; Rep. gr.70.
  Note
The air duct from duct -B- to the right dash panel vent is secured with two bolts. To unfasten, only remove the bolt which is screwed into the dash panel cross-member from underneath and thus accessible.
–  Remove the air duct -B- to the right dash panel vent (front passenger side).
–  Remove the air intake box → Chapter.

–  To prevent interchange, mark the connector -A- (to the right centre vent control motor -V111-) and -B- (right footwell flap control motor -V109-).
–  Unplug the connectors -A- and -B-.
–  Unplug the connector from the evaporator output temperature sender -G263- → Chapter.
–  Unfasten the wiring -D- from the attachment points at the mounting plate -J-.
–  Carefully unfasten the various connecting rods (from -E- to -H-) from the levers at the corresponding flaps.
  Note
t  The connecting rods (from -E- to -H-) are clipped in at the levers. Unclip carefully to avoid damaging the lever.
t  Different versions of the levers and connecting elements are fitted at the air conditioning unit depending on the production period → Chapter and → Electronic parts catalogue.
–  Remove the bolts -C-.
–  Detach the mounting plate -J- (with the control motors and levers, cam plates and connecting rods) from the air conditioning unit.
Installing
Install in reverse order; paying attention to the following:
–  Moisten the guides of the cam plate as well as the pins at the flap levers with a small quantity of grease (e.g. lubricating paste -G 000 150- → Electronic parts catalogue).
–  Check for proper assembly of the levers, cam plates and connecting rods of the mounting plate -J- → Chapter.
–  When installing the mounting plate -J-, pay attention to the pins of the lever -K- and the guide of the cam plate -L-.
  Note
When fitting, make sure the stop of the cam plate -M- is inserted between the two stops at the air conditioning unit -N- and -O- (the cam plate must be able to move over the area marked by the arrow).
–  Fit the bolts -C-.
–  Plug in the connectors -A- and -B- in line with the markings.
–  Secure the wiring harness -D- in the attachment points at the mounting plate -J-.
–  Lay the wiring harness -D- such that it cannot come into contact with moving components (e.g. lever).
–  Re-install all the other parts removed in reverse order.
–  Perform air conditioner basic setting and final control diagnosis → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
  Note
t  The control motors on this vehicle are equipped with electronics. A new control motor only learns its position at the air conditioning unit in the course of basic setting and can then be actuated by the air conditioner operating and display unit, Climatronic control unit -J255- (all control motors are identical at present) → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
t  During basic setting, control motor assignment and adaption are implemented on the basis of the arrangement in the series connection of the wiring. If the sequence is not as specified, the matching of the control motors and thus flap control will not be correct → Chapter (block diagram of air conditioner control motors).
–  Interrogate the event recorder of the air conditioner operating and display unit, Climatronic control unit -J255- and erase any faults displayed → "Guided fault-finding" function of vehicle diagnostic, testing and information system VAS 5051.
–  Switch on the ignition.
–  By making different settings on the air conditioner operating and display unit, Climatronic control unit -J255-, direct the air to the various vents and check whether the flow of air out of the vent actually changes in line with the setting.
