check your DPFE sensor first before you check your egr valve.

DPFE = Delta ( or Differential) Pressure Feedback EGR sensor.
It is a small sensor that tells the vehicles PCM (Powertrain Control Module) how much the EGR valve is open.
Check with your dealer as there may be extended warranty coverage on it.
