Answer
William, Its a good idea to change the relays, especially if they are the original relays.  They will have a date on them.  The breather box is not necessary to change, as they rarely go bad.  You should never clean the EGR valve, you are asking for trouble.  Throtle body cleaning should be done at the 30k service so yes that is wise to do.  Hope this helped.  Roger
