Check whether there are other cylinders with a combustion misfire fault detected by the
tool before starting the following fault finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– programming must be carried out.
– warm engine (coolant temperature 75°C minimum),
– engine running at idling speed with all electrical consumers on for approximately
15 minutes.
Special note:
–OBD warning light illuminated.
1.DEF
NOTESSpecial note:
– As soon as the fault is detected, the injection is cut off on
the faulty cylinder(s) to limit the temperature increase in
the catalytic converter,
– if a fault is present, the OBD warning light flashes.
2.DEFSpecial note:
–the OBD warning light remains continuously lit.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.

The fault is present after starting the engine and under the following conditions:
– there must be no further electrical faults,
– programming must be carried out.
– warm engine (coolant temperature 75°C minimum),
– engine running with electrical consumers on for 15 minutes.
Special note:
–OBD warning light illuminated.
Check the presence and conformity of the fuel in the tank.
If there is no present or stored combustion misfire fault, the misfire was caused by the low fuel level.
Clear fault DF109.
AFTER REPAIREnsure that all the faults have been dealt with.
Do not clear the programming.
To check that the system has been repaired correctly:
– there must be no further electrical faults,
– programming has been carried out,
– warm engine (minimum 75°C).
– running at idle speed with all electrical consumers drawing power for 15 minutes.
If the fault reappears, continue the fault finding procedure.
