Additional information:
t  → Current flow diagrams, Electrical fault finding and Fitting locations
t  → Air conditioning with refrigerant R134a; Rep. gr.00
  Note
t  A plate fitted in the engine compartment indicates the type of refrigerating agent and amount in the system.
t  When the control lamp does not illuminate after pressing the AC button, a fault may be registered in the control unit. Call up the error memory with the Vehicle diagnosis, testing and information system -VAS 505X- (or successor models). If the error entry „Initial commissioning of the air conditioning compressor not performed“ is displayed, the basic settings and an adaptation of the „Initial commissioning of the air conditioning compressor“ must be carried out in the guided fault finding or guided functions.
t  If a new air conditioner control unit -J301- is installed, the setting „Initial commissioning of the air conditioner compressor“ must be performed in the guided fault finding or in the guided functions.
