What to do with Fault P0404

I have this fault which is P0404, which is saying " Exhaust Gas Recirculation insufficent flow "

Would that mean my EGR needs a good clean on the exhaust/soot side or is it some thing else I need to do.

The alarm does reset, normally appears when engine is not warmed up, when warmed up resets easily.

Any help much appreciated.

afaik, could be the EGR system is clogged ot perhaps the solenoid is not fully opening.
