REMOVAL
Put the vehicle on a 2 post lift.
Disconnect:
- the battery,
- the relay plate and the engine connection unit
electrical connector,
98756R
- the connectors of the ignition module and the
HT coil wire,
- the oxygen sensor connector,
- the accelerator and clutch cables.
Drain:
- the cooling circuit,
- the engine if necessary,
- the gearbox (by removing the cover) if
necessary.
Remove:
- the earth strap,
- the air filter,
- the nut and the eccentric bolt (1) (remove
using a roll pin punch) from the steering shaft
yoke after having pushed the protector back.

F8Q engine
- the pipes and connectors for the fast idle and
EGR solenoid valves,
- the brake servo pipe,
- the accelerator and clutch cables,
- the diesel fuel filter connector,
- the compressor feed wire (if fitted).
Remove:
- the cooling assembly (see section 19
"Radiator"),
- the alternator belt (see section 16),
- the compressor mounting bolts (if fitted) and
attach it to the front cross member.
NOTE: cut the base of tool Mot. 1159 to 30 mm.

SPECIAL NOTES FOR MULTIPOINT INJECTION
•55 track SIEMENS FENIX 5 computer.
•Injection cylinder by cylinder (sequential).
•Static ignition with two coils.
•Canister bleed solenoid controlled by RCO signal.
•Idle speed correction depending on:
- battery voltage,
- air conditioning,
- heated windscreen.
•Injection warning light on instrument panel operational.
•Use fault finding fiche N° 27.
•Computer configuration depending on gearbox type (manual gearbox or automatic transmission).
FITTING A 2ND GENERATION ENGINE IMMOBILISER REQUIRES A SPECIAL PROCEDURE FOR REPLACING THE
COMPUTER.
