Detaching air conditioner compressor from holder/attaching (vehicles with 4-cyl. engine)
Detaching
Proceed as follows:
–  Switch off the ignition.
–  Remove the front noise insulation → General body repairs, exterior; Rep. gr.50.
–  Mark the direction of the poly V-belt → Engine, mechanics; Rep. gr.13.
–  Detach the poly V-belt -A- → Engine, mechanics; Rep. gr.13.
   
–  Unplug the connector -A-.
–  Screw out the air conditioner compressor bolts -B-.
–  Detach the air conditioner compressor and swivel away from the engine as far as possible without kinking and straining the refrigerant hoses.
–  Attach the air conditioner compressor to the vehicle (e.g. with a piece of wire) such that the refrigerant hoses are not kinked and strained.
  Caution
Danger of damaging refrigerant lines and hoses.
Take care not to strain, kink or bend refrigerant lines and hoses.
  Note
If the air conditioner compressor cannot be swivelled far enough away from the engine, the compressor unit must be removed → Chapter.
Attaching
Install in reverse order, paying attention to the following:
  A87-10428
–  Before securing the air conditioner compressor, check the position of both dowel sleeves -A- in the holder or air conditioner compressor -B-.
  Note
t  There are different versions of the dowel sleeves -A- (different length). Attention is therefore to be paid to the correct version → Electronic parts catalogue.
t  Pay attention to correct positioning of the bushings -A- as well as to clean contact surfaces. Incorrectly fitted bushings or dirty/damaged contact surfaces -C- at the holder or air conditioner compressor could lead to misalignment between the air conditioner compressor and engine. In the course of operation, misalignment may result in poly V-belt or air conditioner compressor damage.
  A87-10573
–  Tighten bolts -arrows- (tightening torque: 25 Nm).
–  Plug in the connector -1- at the air conditioner compressor regulating valve -N280-.
–  Position the poly V-belt on the poly V-belt pulley → Engine, mechanics; Rep. gr.13.
  Note
t  After attaching the air conditioner compressor, check the routing of the refrigerant lines. They must be inserted in the holders provided (if fitted, depends on engine).
t  Check the refrigerant lines and the corresponding holders for adequate clearance with respect to the other components, ensuring a sufficient distance between the belt, holder and pulley.
–  Interrogate the event recorder of the 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.
