This rattling after a cold start issue was a problem for me as well and my local dealer could never figure out what it was. I think they had the car at least 3 times trying to diagnose it and could never come up with anything. Strange thing, after I got my Evolve tune, the noise went away and I've never heard it since. Could it be related to the delete of the cold start in the programming?
