TEST 7 Incorrect injection quantity
NOTESConditions prior to test:
The entire low pressure system must be in good condition.
Check the sealing of the high pressure pipes and unions.
Te s t 3 High pressure fuel pressure solenoid valve check is OK.
Test 4 High pressure pump (HPP) and fuel flow solenoid valve check is OK.
Te s t 5 Rail high pressure regulation circuit check is OK.
All the electrical consumers are switched off.
Air conditioning is switched off.
Cause:
The engine runs poorly at idle speed, possibly emits white smoke.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Ignition off.
Measure the resistance at the injectors.
The reference resistance is between 150 and
250 kΩ.
Measure at ambient temperature (approx. 20°C),
allow the engine to cool down for at least
30 minutes.
Are the resistances correct?
YES
NOReplace the corresponding injectors.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 9 Particle filter history
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Note:
The flow chart below enables the driving profile and the reasons why the warning light
illuminates to be analysed:
Vdiag 49 and 4D only.
Using the diagnostic tool , read parameters PR836 to PR845 Saved particle filter warning light no. 1 to no.
10 of the subfunction Differential. filter history.
Among these parameters PR836 to PR845:
●Select the record with the highest mileage. This is the “Last saved particle filter warning light”.
●Write the parameter code on the Repair Order with the corresponding last mileage value.
Example: PR836 = 2794 miles (4657 km)
Use the diagnostic tool to read parameters PR794 to PR803 Failed regeneration records No 1 to No 10 in the
sub-function: Particle filter history.
Select from parameters PR794 to PR803 Failed regeneration records No 1 to No 10, any parameters that
occurred between the Last particle filter warning light record and the Last particle filter warning light record
less 120 miles (200 km).
Example: 2674 miles (4457 km) < PR801 = 2760 miles (4600 km) < 2794 miles (4657 km)
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
