TEST 13 Diesel fuel conformity check
WARNING
– During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– guard against petrol splashes caused by the 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 (for 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 litre fuel sample from the diesel filter outlet (see MR 364 (Mégane II) or 370 (Scénic II), 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 let it settle for approximately2 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).
