Hey there, the sound you may be hearing is coming from the A/C system expansion valve when Freon going through it. You may have an A/C system that is a little low on Freon, and needs to be checked for leaks and topped off if no leaks are found. I recommend having a mechanic diagnose the EGR code and sound for you in person to have this resolved.
