AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
–the level 1 warning light is lit,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switching off the ignition and
waiting for 1 minute),
– the particle filter fault finding procedure is inhibited,
– particle filter regeneration is inhibited.
Check the condition of the pressure pipe between the particle filter upstream take-off point and the differential
pressure sensor.
Check that the pipe is not crushed, blocked or pierced.
Check that the differential pressure sensor is correctly positioned and connected (see MR 395, 402, 405, 364, 370,
Mechanical, 19B Exhaust, Particle filter pressure sensor: Removal - Refitting).
Replace the pressure pipe if necessary.
