CHECKING
To ensure the correct operation of the anti-pollution
system, the oil vapour rebreathing circuit must be kept
clean and in good condition.AOil vapour rebreathing pipe for the bottom of engine

REMOVING THE VALVE
The EGR valve is an interference fit in the intake manifold.
To facilitate its replacement it is preferable to remove the manifolds.
PURPOSE OF THE EGR SYSTEM
The recirculation of the exhaust gases is used to reduce the nitrogen oxide
(NOx) content of the exhaust gases.
The passage of gas is authorised by the control of an electromagnetic valve by
the injection computer.
