●Particle filter regeneration failed - run test Temperature upstream of turbine too low: regeneration has
failed because the temperature upstream of the turbine is too low. Run Test 8 Temperature upstream of
turbine too low.
In all cases, carry out the following operations:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and the computer supply.
– switch on the ignition and establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
– depending on the operation performed, select After particle filter regeneration with diagnostic tool, or After
particle filter replacement
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and the computer supply.
–Then switch on the ignition again, clear the present or stored faults from the computer memory (operation
to be carried out within 3 minutes of switching on the ignition).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply test procedure 12 Manual clearing of the weight of soot.
If DF308 Particle filter clogged or DF312 Speed request is still present, contact Techline.
Note:
It is essential to change the engine oil and the oil filter in the following cases:
– following an After-Sales regeneration only if a message on the CLIP diagnostic tool requests it,
– following particle filter replacement,
after a second regeneration (when two successive regenerations).

After using one of these 2 commands:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–Then switch on the ignition again and clear the present or stored faults from the computer memory
(operation to be carried out within 3 minutes of switching on the ignition).

IMPORTANT
When reinitialising injectors, do not forget that cylinder no. 1 is located at the flywheel end.

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.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Take a 1 l fuel sample from the diesel fuel filter outlet (see MR 364 (Mégane II ph2), Mechanical, 19C, Tank,
Fuel tank: Draining, or MR 370 (Scénic II ph2), Mechanical, 19C, Tank, Draining the fuel tank), using a
pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let the fuel settle for approximately 2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 364
(Mégane II ph2), Mechanical, 19C, Tank, Fuel tank:
Draining, or MR 370 (Scénic II ph2), Mechanical, 19C,

Check the fuel temperature by immersing a thermometer in the plastic cup.
End of test. The fuel is not correct.
If the fuel weight is less than the minimum value then there is petrol in the diesel fuel.
If the fuel weight is greater than the maximum value then there is oil in the diesel fuel.
Drain the fuel circuit, including the tank (see MR 364 (Mégane II ph2), Mechanical,
19C, Tank, Fuel tank: Draining, or MR 370 (Scénic II ph2), Mechanical, 19C,

Note:
If the weight measured reaches the limit values, the measurement can be performed with a 2230 ml plastic cup
(part no.77 11 171 414) and its cover (part no.77 11 171 417):
- Carry out a quick test drive in order to mix the fuel, then remove 2 l of fuel.
- Perform the test again and check the results by multiplying the limit values by 2.

Note: In certain cases, this procedure is to be carried out only after replacement of the particle filter or after an
After-sales regeneration of the particle filter.
– Start the engine.
– Raise the engine coolant temperature.
– Read the coolant temperature with the PR064 Coolant temperature until a value greater than 65ºC is obtained.
– Accelerate the engine to 4000 rpm and maintain this speed for 5 minutes.
–After 5 minutes, release the accelerator and stop the engine.
– Switch on the ignition.
– Run command SC036 Reinitialise programming and select After particle filter replacement or After particle
filter regeneration (as appropriate).
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
– Then switch on the ignition again and clear the present or stored faults from the computer memory (operation
