CHECKING THE OIL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 453-01 Hose clamp pliers
Dir. 1204 Pressure test union
Dir. 803 Metric thread union
Fre. 1085
or Pressure gauge
Fre. 244-03
Fre. 284-06 Connecting pipe
Fit clamp Mot. 453-01 to the low pressure pump
hose.
Disconnect the high pressure pipe (take
precautions to catch the oil which will run out).
Insert union Dir. 803 (metric thread) between the
pipe and the pump.
For engines where it is fitted, remove the
pressostat on the rigid pipe (high pressure).
Connect the pressure test union
Dir. 1204 and the oil pressure gauge
Fre. 1085 (or Fre. 244-03 + Fre. 284-06).
77840R1
Connect pressure gauge Fre. 1085 (or Fre. 244-03
+ Fre. 284-06).
Remove clamp Mot. 453-01.
Top up the pump level and run the engine to
check the pressure.
Wheels in straight line:
Regardless of engine speed, the pressure should
not exceed 5 to 7 bars.
Full lock to one side:
Hold the steering at full lock, the maximum
pressure should be 79 to 86 bars.
This operation should not be prolonged to avoid a
high increase in the oil temperature.
Remove union Dir. 803 and pressure gauge
Fre. 1085 or Fre. 244-03 , cutting the supply to the
pump with clamp Mot. 453-01.
Reconnect the high pressure pipe and remove
clamp Mot. 453-01.
Top up the oil in the reservoir.

SPECIAL NOTES FOR BOSCH MONOPOINT INJECTION
• Use the XR25 with the latest cassette and fiche n° 28.
Read the computer Part Number using code G70*.
Erase the memory using code G0**.
• Injection warning light operational (see principle of ignition section).
• Maximum engine speed before ignition cut-out: 6 500 rpm.
• Corrected idle speed after operation of the air conditioning: 900 rpm.
• Corrected idle speed with wheels at full lock (power assisted steering pressostat information) : 825 rpm.
• Canister bleed solenoid valve controlled by RCO signal depending on engine operating conditions (the
valve is not operated for no load).
• If there is a fault with the absolute pressure sensor, the manifold pressure is recreated depending on the
throttle position and the engine speed.
• Reading of the default values from the air temperature sensor (#03) or coolant temperature sensor (#02),
not the values taken in defect mode by the computer when they are recognised as being faulty.
• There is a+after ignition input (track 30) to inform the computer that the ignition has been turned off
while it remains fed for a few seconds to reposition the idle speed micromotor.
(Avoids false detection of a fault in the engine immobiliser system).

ATTENTION :
to prevent any damage being done to the rota-
ting switch under the steering wheel, please fol-
low these instructions :
- before releasing the steering column and the
rack, the steering wheel MUST be immobilised,
wheels straight, using the "steering wheel
locking" tool throughout the duration of the
repair,
- any doubts regarding the correct centring of
the rotating switch means that the steering
wheel has to be removed so as to apply the
centring method as described in chapter 88
"AIR-BAG".
REMINDER: in this case, only qualified personnel
who have received specific training may under-
take this work.
