1. DEF: Signal outside upper limit
NOTESPriorities when dealing with a number of faults:
Deal with faults stored in the computer first.
Ask the customer about vehicle usage: driving style, type of journey, etc.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– the EGR function is inhibited,
– the vehicle performance is reduced,
– the level 1 warning light is lit and a warning message (or light) is displayed on the
instrument panel.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
Carry out an After-Sales regeneration (before and after each regeneration, check the oil and diesel fuel levels).
Run command SC017 Particle filter regeneration (see Interpretation of commands).
Use ALP 21: Particle filter warning light lit.
Deal with the interpretation of fault DF1003 Particle filter differential pressure sensor circuit.
Check the exhaust system.
Deal with the interpretation of fault DF1000 Particle filter upstream temperature sensor circuit.
Deal with the interpretation of fault DF1007 Catalytic converter 1 downstream temperature sensor circuit.
Deal with the interpretation of fault DF999 Particle filter downstream temperature sensor circuit.
Deal with the interpretation of fault DF652 Turbine upstream temperature sensor circuit.
Carry out Te s t 1 0: Air Chain at the level of the turbocharger.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
Explain to the customer how the particle filter system works.

ALP 19 Oil leak from the turbocharger
NOTESThis ALP concerns the following customer complaint:
– Oil leaks from the turbocharger.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a turbocharger fault, the oil leak can arise from the area around the
turbocharger.
According to the vehicle type, maximum visual access will either be from above or from below.
1-Do not start the engine.
Check the area around the turbocharger and identify the origin of the leaks.
Clean the oil traces on the turbocharger.
2- Start the engine and let it warm up for several minutes.
IMPORTANT
If the air filter was removed previously, refit it before starting the engine (risks foreign matter entering the air inlet
circuit).
Accelerate with no load several times, progressively increasing the duration before releasing the accelerator
pedal.
Visually inspect the exterior condition of the fuel supply pipes and the turbocharger oil return and the area around
it.
Identify the origin of the leaks.
Is an oil leak present at the air compressor inlet or outlet?
YES
Check the air compressor inlet or outlet
Check for a loose interface (inlet or outlet) that is the cause of the air
leak.
Note:
It is normal to find oil traces inside the pipes at the turbocharger inlet
or outlet, because the air entering the compressor is laden with oil
from the
engine rebreathing circuit.
Is the suspected interface properly tightened?
YES
Replace the pipe concerned (see MR 364 (Mégane II), 370 (Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio
III), Mechanical, 12B, turbocharging).
NO
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

SECTION D - Procedure for switching off the particle filter message or warning light on the instrument panel
Certain types of driving can trigger the activation of the particle filter warning light or message. This fault occurs
when the weight of soot is more than 30.8 g.
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. Making sure the engine is warm
2. Drive at a speed greater than 24 mph (40 km/h) for 2 minutes to initiate the regeneration process.
Initiating regeneration Minimum speed Minimum time
All vehicle types 24 mph (40 km/h) 2 minutes
3. Then drive at a speed of more than 24 mph (40 km/h) until the Particle Filter message or warning light on the
instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
(without stopping the engine) or to leave the engine running at idle speed for an extended period of time. The
regeneration time depends on the vehicle and driving conditions but normally lasts about 20 minutes.
Regeneration duration Minimum speed Average time
All vehicle types 24 mph (40 km/h) 20 minutes
4. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. To carry out After-Sales regeneration:
check the oil level and remove some oil if the maximum level has been reached, then apply the procedure for
command SC017 Particle filter regeneration (see Interpretation of commands).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
