– drain the diesel filter unit (seeMR 364, 13A, Fuel supply),
– clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
If the fault does not recur, end the fault finding procedure.
C) If the fault recurs:
–Check the continuity and the absence of unwanted resistance on the connection between:
