WARNING
This fault only appears in Vdiag 48.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– a road test,
– an actuator command AC002 EGR solenoid valve.
Special notes:
The EGR and turbocharging functions are inhibited.
The level 1 warning light comes on.
Use bornier Ele. 1681 for all operations on the injection computer connectors.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Clear any stored faults.
Run command RZ002 EGR Adaptives to reinitialise the valve operating values.
Switch off the ignition and wait for the engine immobiliser warning light to start flashing.
Switch the ignition on again and check the system faults.
If the fault is still present:
– remove the EGR valve, and then reconnect it,
– check that the movement of the valve is not being blocked by a particle,
– check that the valve is not jammed or stuck in one position,
– run command AC002 EGR solenoid valve,
– check the movement of the solenoid valve,
– check that the solenoid valve is completely closed,
– if there is no movement, or if the valve is seized and cannot be repaired, replace the EGR solenoid valve.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
