code P0401 EGR flow insuffcient
I got this the second time now within 3 months. Do I need to get a new EGR valve or where may this code come from. Where is the flow actually detected and how?
Thanks!

Have you tried anything with it yet?
I figured it's easier to ask than to go look at all your old posts
The most common problem that causes the P0401 is the DPFE sensor but you could have a bad EGR valve or plugged ports in the intake etc.
