NOTESPriorities when dealing with a number of faults:
Deal with faults DF011 Sensor feed voltage no. 1 and DF046 Battery voltage first,
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– the ignition is switched on,
– starting the engine,
– a road test.
Special notes:
If the fault is present:
– the EGR function is inhibited by the engine management computer,
– engine torque limited,
– turbocharging pressure is in defect mode,
– turbocharger cut-off in defect mode,
– cut-off of the EGR valve in defect mode,
–PR041 Turbocharging pressure = 750 mbar,
–the level 1 warning light is on.
