Part C:
Confirmation of flow correction fault finding for each injector (individual correction):
Clear the faults and run a test with the engine at idle speed and the fuel temperature > 50°C, check that no faults
appear on the diagnostic tool and that the correction values do not reach X = ± 5 mg/stroke to confirm the repair.
– If one or more cylinders have flow correction values for an injector which exceed X = ± 5 mg/stroke, follow the
fault finding procedure described in Part A: Fuel regulation balance check for each injector (individual) of
Test 10.
– Otherwise, follow the fault finding procedure described in Part D of Test 10.
Part D:
Injector nozzle sealing check:
Check the level and condition of the engine oil:
– If there is contamination from the diesel fuel, the leaking injector nozzle will be "greasy".
– Disconnect the preheating relay.
– Ensure that this is not caused by rising engine oil by checking the engine compression values.
– Check the condition of the heater plug: this must not be wet. If it is, change the defective injector.
– If the engine compression values are correct: locate the faulty injector by looking at the condition of the cylinders
and the pistons through the heater plug wells (greasy cylinder, overheating, signs of damage, etc.).
– If the cylinder - piston examination is not conclusive, remove the injectors and change the one with the greasy
nozzle.
– If the fault finding checks do not enable the engine to be repaired, contact the Techline.
After replacing the injector, follow the injector code programming procedure (see Replacement of components),
run SC036 Reinitialise programming, and select the number of the injector replaced.
Note:
Before replacing an injector, check for the sealing washer and its conformity (see Fault finding chart ALP4 Poor
performance).
IMPORTANT:
When removing / refitting injectors, follow the cleanliness and safety instructions (see MR 395 (Laguna II ph2),
402 (Vel Satis), 405 (Espace IV Ph2), 364 (Megane II ph2), 370 (Scenic II ph2) Mechanical, 13B, Diesel
injection, Diesel injectors: Removal - Refitting).

Fault finding – Test13B
TEST11 Temperature upstream of turbine too low
Perform a complete fault finding of the
injection computer using the diagnostic tool.
Are there any present or stored faults?Apply the procedure for dealing with the
associated faults.
Run Test 1 Exhaust system check
Is the exhaust pipe correct?
Repair then carry out another particle filter
regeneration.
Run command SC017 "Particle filter
regeneration" (see Interpretation of
commands).
If the second regeneration is successful, it is
essential to change the engine oil and replace
the oil filter.
If the second regeneration fails, contact the
Techline. Apply Test 4 Turbocharged air inlet circuit
check.
Is the inlet circuit in order?
Run Test 4 Air flowmeter
Is the air flow sensor correct?
Run Test 10 Poor injector operation
Are the injectors correct?
Contact the Techline.
