I had my EGR valve pop off and after reaserching it on the internet I found that although there was never an acutal RECALL, the dealer is replacing these for free! Thank God I looked first, because when I made the initial appointment they were going to charge me for it.........of course I reminded them of the not-yet-a-recall that I found.......and they waived all fees!
But, yeah, dont pay for that my friends!
