Possible complaints

Note
For all complaints marked with an *
⇒ "9 Check the pressure in the refrigerant circuit (with the A/C
service station)", page 71
♦ The cooling system has failed completely.*
♦ Insufficient cooling capacity for all vehicle speeds or engine
speeds.*
♦ No cooling or insufficient cooling after a few kilometres of driv‐
ing.*
♦ The AC compressor, the air conditioner magnetic coupling -
N25- or the regulating valve for compressor of air conditioning
system - N280- are switched off, due to a too high or too low
pressure, by a low pressure switch for air conditioning system
- F73- , , the high pressure switch for magnetic coupling -
F118- , the air conditioner pressure switch - F129- or from the
Climatronic control and display unit for air conditioner - E87- ,
or the Climatronic control unit - J255- .*
♦ No or a strong decrease of fresh air supply after a few kilo‐
metres of driving (evaporator iced up).*
♦ Odour from the heating and air conditioning unit

In addition, the following complaints may still arise:
The air conditioning compressor makes noises
– Tighten the fixing screws for the AC compressor and the AC
compressor bracket with a torque wrench.
– Check the routing of the coolant pipes, they must not be flush
with other components and must be installed free of tension
(align if necessary).
Immediately after switching on the air conditioning system and/or
when cornering or braking, noises occur (refrigerant hammering):
– Drain refrigerant circuit, evacuate and fill again (too much re‐
frigerant in the circuit).
