Does the engine start?–Fit Mot. 1760 as shown in the tool fitting procedure.
– Start the vehicle or do a starting sequence of 15 s (with ignition
key).
– Measure the length travelled by the diesel fuel in the pipes of the
Mot. 1760.
– Replace the injector if the length travelled by the fuel is more than
10 cm compared with the average of the other three injectors.
– The injector return pipes must be fitted to the injectors.
– Start the engine.
– Display the sub-function Fuel circuit in the CLIP diagnostic tool.
– Raise the temperature of the engine.
– Read the diesel fuel temperature with the PR063 Fuel temperature until the diesel fuel temperature is greater
than 50°C
– Switch off the engine.
–Fit Mot. 1760 as shown in the installation procedure (see step 1).
– Check the value of the PR038 Rail pressure.
– Ask another Cotech to monitor the rise in fuel in the cans during engine turnover, as one of the cans will fill up
quickly if one of the injectors is leaking.
– Start the engine.
– Accelerate the engine until the pressure in the rail is 550 bar:
– if the engine speed is less than 3,000 rpm, maintain this pressure.
– if the engine speed is more than 3,000 rpm, reduce the engine speed until the rail pressure is 500 bar
and maintain this pressure.
– Maintain these conditions for 1min.
– Release the accelerator pedal and maintain the idle speed for 10 seconds.
– Switch off the engine.
– Measure the quantity of fuel contained in each measuring cylinder.
– Replace the injector if the quantity of fuel is more than 50 ml.
– Remove Mot. 1760 as shown in the tool removal procedure (see step 3).

IMPORTANT
Use a cleaning cloth (part number 77 11 211 707) to absorb fuel run-off.
Disconnect the pipe from an injector:
– press on the injector clip,
– pull vertically on the end piece of the pipe of the tool Mot. 1760 while putting a rag on the end piece to prevent
drips.
Lift the end piece vertically so that the fuel contained in the pipes flows into the measuring cylinders of tool
Mot. 1760.
Remove the other 3 pipes using the same procedure.

TEST11 Diesel fuel conformity check
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,
Tank, Draining the fuel tank).

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,

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.

TEST12 Manual clearing of weight of soot
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
to be carried out within 3 minutes of switching on the ignition).
