TEST5 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.
Remove 1 L of fuel at the diesel filter outlet (see MR 364 (Mégane) or 370 (Scénic), Mechanical, 19C, Tank,
Fuel tank: Draining), 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 allow it to 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)
or 370 (Scénic), Mechanical, 19C, Tank, Fuel Tank:
Draining).

TEST5
CONTINUED
Weigh the diesel fuel and note the fuel weight after subtracting the weight of the empty plastic cup and its cover.
Does the fuel weight fall between the minimum and maximum weights given in the table below?

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) or
370 (Scénic), Mechanical, 19C, Tank, Fuel Tank: Draining).
Note:
If the weight measured reaches the limit values, the measurement can be performed with a 2230 ml (part no. 77
11 171 414) plastic cup with a 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.
