Summary

Engine running rough or laboring following an extended period of short journeys. This is often caused by soot build-up on the EGR (Exhaust Gas Recirculation) which sticks the valve in the closed or more importantly open condition.

Fault code	Fault	Possible Causes
P0400	No exhaust gas recirculation. Expected performance not reached. Engine goes into limp home mode.	The EGR valve does not open
P0401	Too little exhaust gas is being recirculated	The EGR valve does not open wide enough. Width restricted by impurities (carbonization). EGR valve opening time too short Air mass sensor defective or soiled.
P0402	Excessive exhaust gas recirculation	The EGR valve deviates from the correct point when open. The valve does not close properly. The Air Mass sensor is defective.
P0403	EGR signals wrong or implausible	Wear or soiling of the potentiometer in the EGR valve assembly. The temperature sensor is defective.
P0404	Exhaust gas recirculation is out of correct position. EGR signals are wrong or implausible.	Wear or soiling of potentiometer, pressure sensor, temperature sensor or Air Mass sensor.

Resolution

One of the most frequent causes of problems with EGR valve operation is deposits in the valve or seat.

The valve can be stuck closed, or
deposits have caused the opening width to be reduced, or
the valve does not open completely.
