Conditions for Fault to clear:	Driving with the engine hot for 5 minutes
Downgrade Modes whilst Fault is active:	Deactivation of the strategy for monitoring the current of the fuel flow regulation valve Increase in the engine idling speed Deactivation of the kick-down for automatic gearboxes Deactivation of the injector resetting strategy Limitation of performance Reversible deactivation of the vehicle speed limiter Reversible deactivation of the vehicle cruise control Deactivation of the after-sales test for detection of leaks on the diesel fuel high pressure circuit Switching on of the warning lamp and/or warning message: Warning lamp MIL "SERVICE" warning lamp
Symptoms:	Engine hesitating, cutting out Noise Smoke from the exhaust Starting problem Lack of power
