CAUTIONS:
The refrigerant oil top-up quantity must not exceed the refrigerant oil fill quantity.
If other A/C components are being renewed in addition to the A/C compressor, there is no
need to top up with additional refrigerant oil, apart from filling the compressor.
Because the fill quantities differ, the refrigerant oil must be drained from the new A/C
compressor.

• The refrigerant line between the fixed orificetube and the evaporator must be cold from the
point where the fixed orifice tube is installed.
Depending on the weather, the refrigerant line
may also have ice on its surface.
• The refrigerant line between the evaporator and the A/C compressor including the dehydrator
must be cold.
Evaporator outlet line temperature test
To test the power of the A/C system, the
temperature at the evaporator outlet line must be
measured. To do this, the following preconditions
must be met:
• Open all windows.
• Set the air distribution to the defrost/dashboardposition and open all the ventilation nozzles.
• DO NOT switch on recirculated air.
• Select lowest blower switch setting.
• Select lowest temperature setting.
NOTE: The temperature measurement cannot be
done with a thermometer which makes no contact.
The surface reflection from the metal line may
cause incorrect readings.
Connect the temperature sensor (Fluke 80 PK-8)
to the outlet line of the evaporator. Locate the
temperature sensor as close as possible to the
evaporator. Connect the temperature sensor to the
multimeter.
Start the engine and allow it to run at idle speed
for several minutes.
Switch on the A/C.
After three minutes, measure the surface
temperature of the evaporator outlet line.
If the temperature measured is 4° C or lower, the
A/C system is OK. If the temperature is higher, the
A/C system may be under-filled. For further
information, refer to
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging (412-00
Climate Control System - General Information,
General Procedures).
Frequent faults and their causes
If the cooling power of the A/C system is not
adequate, make certain that the temperature
control flap(s) is/are operating correctly. • No or poor cooling performance:
– Blockage or narrowing of a refrigerant line orin the dehydrator. The location of the
blockage or narrowing can easily be located
by temperature comparisons at the
refrigerant lines and the dehydrator. The
blockage or restriction is located at the point
where the temperature difference is
identified. Note: A temperature difference
in the area of the fixed orifice tube is
normal. If the location of the blockage or
narrowing is found, check the corresponding
component and renew as applicable.
• Sudden drop in cooling performance (after the air conditioning has been switched off for
approx. 5 minutes, the cooling performance
returns to normal):
– The cause is an iced-up fixed orifice tubebecause of moisture in the refrigerant circuit.
In order to ensure that moisture is completely
removed from the refrigerant circuit, the
dehydrator should be renewed and the
evacuation time should be extended to 2-3
hours. For further information
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging
(412-00 Climate Control System - General
Information, General Procedures).
Sequence of A/C Request Signal
NOTE: The electronic automatic temperature
control (EATC) module is integrated into the air
conditioning control assembly.
NOTE: The generic electronic module (GEM) is
an integral part of the central junction box (CJB).
After actuating the A/C ON/OFF switch integrated
into the A/C control assembly, an A/C request
signal is sent from the A/C control assembly
(vehicles with EATC: EATC module) to the GEM.
From there, the signal is sent to the instrument
cluster via the MS-CAN bus. A gateway is installed
in the instrument cluster, which establishes the
connection between the MS-CAN bus and the
HS-CAN bus.
After the signal has been converted in the gateway,
it is relayed to the powertrain control module (PCM)
via the HS-CAN bus. Once all the required
parameters have been met, the PCM switches on
the refrigerant compressor and thus the A/C system
via the A/C clutch relay.

Climate Control – Overview
Pollen filter
E97258
The pollen filter must be changed at intervals in
accordance with the service schedule. A special
production pollen filter is installed in the factory,
and this must be cut through when the filter is
changed. The service pollen filter is flexible and
can be pushed together during installation or
removal.
Heat exchanger
E97249
The heat exchanger is accessible from the
right-hand side of the climate control housing (LHD
and RHD). It can be removed and installed with
the climate control housing still installed in the
vehicle. During removal, the coolant pipes of the
production heater core must be sawn through.
During servicing, a heater core with separate
coolant pipes is installed.
Evaporator assembly
E97250
The evaporator is located on the right-hand side
of the climate control housing (LHD and RHD). It
can only be removed and installed with the climate
control housing still installed in the vehicle, and the
heat exchanger must be removed at the same time.
Blower motor
CAUTION: Make sure that the blower motor
and fan assembly is placed on the bench
with the fan pointing upwards.
412-131
E101398
To prevent damage to the fan wheel vanes, the
fan wheel must not be touched. For this reason, a
special tool (412-131) has been introduced for
removal and installation of the blower motor. This
tool is pushed onto the central shaft in order to lift
out the blower motor.

The engine driven refrigerant compressor (2) sucks
in gaseous refrigerant from the suction accumulator
and compresses it. The temperature of the
refrigerant rises to a value between 70 °C and 110
°C. It passes to the condenser (1) under high
pressure.
At this point heat is drawn from the refrigerant by
the air being forced past the cooling fins. Because
of this heat loss, the refrigerant liquefies and leaves
the condenser.
A fixed orifice tube (6), which separates the
refrigerant at high pressure from that at low
pressure, is located between the condenser and
the evaporator (5). This fixed orifice tube slows
down the flow of the refrigerant from the compressor, so that pressure builds up in the
condenser.
After passing through the fixed orifice tube the
liquid refrigerant expands in the circuit to the
evaporator, where it becomes gaseous. This
causes heat to be extracted from the air coming
into the vehicle. The air cools down, and excess
moisture contained in it is condensed and is
drained off. The refrigerant coming from the
evaporator flows into the refrigerant accumulator
and is again sucked in by the refrigerant
compressor.
The system is protected by a high-pressure limiting
switch, in order to prevent damage by excessive
pressure (e.g. because of overfilling with
refrigerant). If the pressure exceeds the maximum
