Hello,

The EGR and EGR solenoid are separate parts.
Anytime you have a EGR related trouble code, it is a good idea to service the EGR valve. As a dirty valve can trigger codes.
If it has not been done in a while it is a good idea to clean the valve and the tube of the EGR system.

I have attached the diagnostics procedure for the code P0403. This will walk you through the steps to determine the faulty part.

Please let me know of any questions.

Thank you.
