EGR (Exhaust Gas Recirculation) Issues associated with EGR (Diesel):

Carbon build up/blockages are the biggest threat to the efficiency of the EGR system.

This issue is mainly caused by recirculating hot exhaust gasses back into a cold intake. In this issue the carbon content in the gas solidifies and forms in the EGR valve itself, the intake manifold and the intake ports. Temperature control of the recirculated exhaust gas is key to reducing this issue.
