TEST 9 Diesel filter check
Check the conformity of the diesel filter. Replace the filter with an original part (see MR
364 (Mégane II) or MR 370 (Scénic II),
Mechanical, 13A, Fuel supply, Fuel filter:
Removal - Refitting) Is the diesel filter in order?
– Switch off the ignition and analyse the diesel fuel in the diesel filter.
– Disconnect the diesel supply and return hoses from the filter.
– Block the filter inlets and outlets straight away with appropriate plugs.
– Remove the filter from its holder and shake it firmly while holding the caps in place. Tap the edge of the filter
with a screwdriver handle to detach any contamination. Empty the contents of the filter into a glass container by
lifting a protective plug, then loosening and completely removing the bleed screw.
Is there a deposit of black particles at the bottom of the container?
Pass a magnet beneath the container to collect
all the metal particles. Take the magnet away
from the container.Diesel filter in good order.
Do the particles collected, using the magnet,
cover a surface area greater than 1 cm
2?
Replace the entire injection system Diesel filter in good order.
