Note
♦
Overfilling with refrigerant oil can occur if the refrigerant oil
level was not checked after the air conditioner compressor
was renewed.
♦
If the air conditioner compressor is not to be replaced, drain
refrigerant oil from air conditioner compressor via the drain
plug. From the total amount of refrigerant oil, fill 50 g direct into
air conditioner compressor and fill remainder in refrigerant cir‐
cuit according to ⇒ vehicle-specific workshop manual .

valve and reservoir (with internally regu‐
lated air conditioner compressor)
Note
♦
Connecting air conditioner service station ⇒ page 126 .
♦
Observe the test prerequisites ⇒ page 127 .
– Raise engine speed to 2,000 rpm.
– Observe manifold gauge.
Note
The switch pressures and the versions of switches in the refrig‐
erant circuit are vehicle-specific.
Pressures must be measured at the service connections; the fit‐
ting locations of these connections are vehicle-specific.
