After about 2000 miles suddenly started to sound a little more llke a diesel. Dealer did a injector kill test and determined it was the #3 injector making all the noise. Calls tech line and they say the 05's are noisey because they make more power,and that I have to much warranty left to change a injector because it is a little noisey. So go away and come back when it is broke I guess. My dealer has been good,they cleaned the injectors and set all the valves trying to figure out the noise. I don't mind the noise,it goes away after idle,I was just worried it could be something more serious.
