Whenever the system is opened, the fluid reservoir should be replaced because of the water which has
collected there in the meantime.
EXPANSION VALVE, FUNCTION - GF83.40-P-2123-01GC
Function
When the refrigerant compressor is switched on the pressure in the evaporator drops, thereby causing the
diaphragm (1) to curve downwards. The control valve (3) follows the movement of the diaphragm and presses
the ball (4) out of its seating against the spring (5). The opened valve enables the refrigerant to be sprayed into
the evaporator.
As the diaphragm movement (1) is dependent on both the intake pressure and the temperature at the evaporator
outlet, only the specific quantity of refrigerant, as required for optimum vaporization, is injected.

EXPANSION VALVE, LOCATION - GF83.40-P-2123-02GH
The expansion valve (1) is located on the right at the rear in the engine compartment next to the battery.

OFF . To this end the system uses the residual heat of the engine. The residual engine heat is dissipated to the
coolant and routed through the heat exchanger with the aid of the heating water circulation pump. The air drawn
in by the blower motor is routed around the heat exchanger, whereby it is then warmed up. The heated air is
then routed over the air outlets into the passenger compartment.
The residual engine heat utilization system can only be used when the ignition is switched OFF.
Once the Rest push-button ( ) on the AAC push-button control module (N22) has been pressed the
following program sequence is run:
Blending air flaps are automatically controlled
Heating water circulation pump ON
The blower's control voltage is limited to a maximum value of 5 Volt.
End of program
Pressing the Rest push-button ( )
Timeout of 30 minutes period (repeated operation possible)
Protection against undervoltage at a battery voltage of less than 11 V (LED flashes)
Ignition ON
During the residual engine heat utilization function no function keys are accepted apart from the Rest push-
button ( ) and the set point adjusters.
SAFETY PRECAUTIONS
RISK OF EXPLOSION CAUSED BY WELDING OR SOLDERING WORK ON CLOSED AIR CONDITIONING SYSTEM.
RISK OF POISONING CAUSED BY INHALING OVERHEATED REFRIGERANT VAPORS. RISK OF INJURY TO SKIN AND
EYES CAUSED BY CONTACT WITH LIQUID REFRIGERANT. - AS83.00-Z-0001-01A
Never perform welding work on or near a closed air conditioning system. No smoking or open flames.
Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on
the air conditioning system circuit only after the system has been discharged.
Potential risks
Risk of explosion
When closed air conditionin
g systems (charged or empty) become heated, high pressures are produced that can

Rims
D
When changing wheels, for instance, when replacing steel

wheels with light-alloy rims, ensure that the wheel bolts

required for the spare wheel are stored in a clearly visible

location.

D
Since December 1994 models 202 and 124 with special

equipment light alloy disk wheels, are supplied with a sheet

steel spare wheel instead of a light alloy spare wheel. The

necessary wheel bolts are included with the steel spare wheel.

D
Only use approved Mercedes-Benz rims of the same version.

D
Reinforced steel rims are identified by a sticker on the wheel

disc.

D
The wheel bolts on steel and light-alloy rims should always be

tightened to the specified tightening torque using a torque
wrench.

It is not necessary to retorque the lug bolts after approximately

100 to 500 km.
D

The seat for the tire bead must display no corrosion marks.

D
Before inserting a new rubber valve, clean the contact surfaces

on the disk wheel.

On sheet steel-disk wheel wheel trims must be fitted to support

the rubber valve.


Damaged or deformed rims must not be repaired.

Tire pressure monitor
D
Before replacing a tire, check the date of manufacturer of the

wheel sensor: wheel sensors which are more than 5 years old

must be replaced.

D
Use STAR DIAGNOSIS to read out the actual values of the tire

pressure monitor. Check the remaining life of the wheel sensor

battery, replace the wheel sensor if necessary.
