Re: EGR question
Chances are that the EGR valve itself is not the cause. I'm not a fan of randomly replacing parts but the DPFE sensor is, by far, the leading cause of EGR flow codes. You'll also want to check the 2 hoses that lead from the steel EGR tube to the DPFE - they sometimes crack or melt.
