STOREDLOW FUEL LEVEL MISFIRING
1.DEF: Destructive misfiring
2.DEF: Polluting misfiring
3.DEF: EOBD
NOTESPriorities when dealing with a number of faults:
Firstly, deal with the following faults:
–DF085 Fuel pump relay control circuit,
–DF026 Cylinder 1 injector circuit
–DF027 Cylinder 2 injector circuit, DF028 Cylinder 3 injector circuit,
–DF029 Cylinder 4 injector circuit,
–DF059 Misfiring on cylinder 1,
–DF060 Misfiring on cylinder 2,
–DF061 Misfiring on cylinder 3,
–DF062 Misfiring on cylinder 4,
–DF436 Combustion misfiring detection,
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
1.DEF: As soon as the fault is detected, the injection is cut for the faulty cylinder(s) to
limit the rise in temperature inside the catalytic converter. The OBD warning light
flashes for as long as the fault is present.
2.DEF: The OBD warning light is continuously lit.
Check:
–the level of fuel in the tank,
–the conformity and the grade of the fuel, apply test 1 Petrol conformity check,
–the fuel filter,
–the fuel pump,
–the fuel lines,
–the fuel pressure.
If there is no present or stored misfiring fault, the misfiring was caused by the low fuel level.

STOREDFUEL CIRCUIT OPERATING FAULT1.DEF: Operational fault finding on the fuel circuit should detect a fault on the petrol
system causing the EOBD pollutant emission thresholds to be exceeded.
The on-board diagnostic can detect:
–clogging of the injectors or an injector flow fault,
–a fault in the supply system (pressure regulator, fuel pump, filter, etc.),
–a poor connection in the petrol or injection circuits.
2.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running (wait for approximately
2 minutes).
Check:
–the fuel pressure,
–the fuel filter,
–the fuel pipes,
–clogging of the injectors or an injector flow fault (see MR 392 (Clio III), MR 385 (Modus), MR 411
(New Twingo), or MR 442 (E33), Mechanical, 13A, Fuel supply).
If the fault is still present, contact the Techline.

AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
–there must be no further electrical faults,
–programming has been carried out,
the engine must be warm (minimum 75˚C), and idling, with all electrical consumers
running for 15 minutes.

WARNING
During this operation, it is essential to:
–refrain from smoking or bringing incandescent objects close to the work area,
–protect yourself against fuel splashes due to residual pressure in the pipes,
–wear safety goggles with side guards,
–wear leaktight gloves (Nitrile type).
IMPORTANT
–To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
–To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 l of fuel at the fuel filter outlet, in the engine compartment (see MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 19C, Tank, Fuel tank: Draining), using a pneumatic
transfer pump (part no. 634-200) and place it in 1300 ml plastic cup (part no. 77 11 171 413).
Close the plastic cup with its cover (part no. 77 11 171 416) and let the fuel rest for approximately 2 minutes.
This type of plastic cup is used to prepare paint.
Is the fuel cloudy or does it
separate into two parts?Water is present in the petrol; the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), or MR 442 (E33),
Mechanical, 19C Tank, Fuel tank: Draining).
