Well i don't like to speculate without a code #, but if it is in fact an EGR code, its a fairly simple system. The valve and solenoid are one piece and there are no vacuum hoses for it. If it is an EGR code, either the EGR port is clogged, the valve is faulty or it simply needs to be cleaned. (cleaning it usually does the trick) Without a scan tool its a little difficult to diagnose exactly what the problem is. Before replacing the valve I would suggest removing and cleaning it with some choke cleaner, as the valve is approx $275.
Here is a link to very good video on exactly how to clean the valve.
The code we have is not specific to dirty EGR valve. It said EGR circuit. Are there other EGR related codes that are not dirty valve related? . .
