REMOVAL
I - REMOVAL PREPARATION OPERATION
aLock the airbag computer (see Fault finding - Re-
placement of components) (88C, Airbags and pre-
tensioners).
aDisconnect the battery (see Battery: Removal - Re-
fitting) (80A, Battery).
a
aDrain the coolant circuit using the refrigerant
charging station (see Refrigerant circuit: Drain-
ing - Filling) .
aMove aside the engine compartment bulkhead
soundproofing.aRemove the bolts (1) from the pipe unions on the ex-
pansion valve.
aDisconnect the expansion valve pipes.
aFit plugs into the openings.
aFit hose clamps (Ms. 583) at (2) .
aRemove the clips (3) from the heater hoses.
aDisconnect the heater hoses. Special tooling required

AIR CONDITIONING
IMPORTANT
Consult the safety and cleanliness advice and
operation recommendations before carrying out
any repair (see Air conditioning: Precautions
for the repair) .
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229 or 77 01 476 857 to plug
any openings exposed to the open air. They m ust
be clean. Do not use any which have already
been used to plug a fuel circuit.

WARNING
In order to avoid any refrigerant leaks, do not
damage (deform, twist, etc.) the pipe.
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which
are open to the air.
