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.
Remove 1 l of fuel at the fuel filter outlet, in the engine compartment (see MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 19C, Tank, Fuel tank: Draining), using a pneumatic
transfer pump (part no. 634-200) and place it in 1300 ml plastic cup (part no. 77 11 171 413).
Close the plastic cup with its cover (part no. 77 11 171 416) and let the fuel rest for approximately 2 minutes.
This type of plastic cup is used to prepare paint.
Is the fuel cloudy or does it
separate into two parts?Water is present in the petrol; the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), or MR 442 (E33),
Mechanical, 19C Tank, Fuel tank: Draining).
Visually compare the fuel removed with the correct petrol.
