CASE No. 2: If at least one of the values is less than or equal to - 5 mg/st
– Check the valve clearance.
– Check the level and condition of the engine oil.
– Remove the injector with the largest adjustment.
– If there is contamination via the diesel, check the condition of the cylinder concerned (cylinder, piston, valves).
Use an endoscope if possible.
– Replace only the removed injector, and modify the IMA code using the command SC002 Enter injector codes
(see Interpretation of commands).
–Apply Part B Confirmation of flow correction fault finding for each injector (individual correction) to
confirm the fault finding.
CASE No. 3: If at least one of these values does not stabilise (20 seconds after starting)
– Check the low pressure circuit with test 3: Low pressure circuit check.
– Check the conformity of the fuel by running test 11 Diesel fuel conformity check.
Apply Part B Confirmation of flow correction fault finding for each injector (individual correction) to confirm
the fault finding.
CASE No. 4: If the fuel flow correction values are all correct (between - 5 mg/st and + 5 mg/st)
Apply Part C Measure return fuel flow.
IMPORTANT
When removing/refitting an injector, follow the cleanliness guidelines and safety advice (see MR 364 (Mégane II)
or 370 (Scénic II), Mechanical systems 13B, Diesel injector: Removal - Refitting).
Section B: Confirmation of flow correction fault finding for each injector (individual correction):
Clear the faults and perform a test with the engine idling during at least 5 min, fuel temperature> 50°C.
Check that no fault appears on the CLIP diagnostic tool and that the correction values do not reach ±5 mg/st to
confirm the repair.
If the customer complaint is still present and the fuel flow correction values are between -5 mg/st and +5 mg/st,
apply part A Fuel regulation balance check for each injector (individual), CASE No. 4.
If one or more cylinders has a flow correction value per injector that reaches ±5 mg/st, apply Part A Fuel
regulation balance check for each injector (individual) because one or more injectors might be defective.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
