Hi, got a fault code P0401 EGR system insufficient flow. Mechanic pointed to a flow meter in the hose off the air filter. Do you normally clean them out or replace them? Thanks Rob

Hi Rob this is an EGR fault not an air intake fault id take it somewhere else.

As above.

Its the EGR valve thats at fault thats what the code is telling you. Might get away with giving it a clean and not replacing
