I had some preliminary checks done - the EGR valve is good and tubing not carboned up.

These parts are on back (firewall) side of engine - Can anyone tell me how much work it will bee to access these to replace?

Thanks!
Proceed with caution .
Codes do not say replace parts.
What was the code no.
Egr problems can be in the DPFE sensor or feed pipe or Intake ports stopped up.
What engine and what codes?
