High pressure circuit check
Note:
Depending on the vehicle type, the best visual access will be either from
above or from below.
Visually inspect the condition of the following components:
– outlet pipe of the compressor to the turbocharging air cooler,
– outlet pipe of the turbocharging air cooler to the inlet manifold,
– inlet manifold,
– temperature and pressure sensors.
Is one of these components incorrect (disconnected, cut, bent,
pierced or kinked pipes)?
Replace the defective parts
(see MR 364 (Mégane II) or
370 (Scénic II),
Mechanical, 12B,
Turbocharging). Exhaust system check
Visually inspect the condition of the following engine sections:
– from the exhaust manifold circuit to the turbocharger turbine,
– from the turbine outlet pipe to the end of the exhaust pipe,
– from the inlet manifold to the EGR valve
– check that the temperature and pressure sensors are connected.
Do some of these components have black or white marks on them?

HIGH PRESSURE PUMP
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter),
– positioning and clogging condition of the filter cartridge,
– Positioning and condition of the seals.
– if there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
●Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely with
an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and seal it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container of approximately 5litres.
– Disconnect the diesel return pipe at the diesel temperature sensor (pump return and injector return join), and block
it using a plug.
– Connect a transparent pipe to the union of the diesel temperature sensor, and insert the other end in the container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect
the various pipes of the low pressure circuit and
repeat the fault finding chart fault finding or of
the fault that referred you to this test.
