Took mine in for romping and smoking white smoke at start up. Needed a new FICM. I have no kitty, fixed under warranty, they didn't even question it.
Mine didn't smoke when warm however. Are you gettign white or black smoke when warm? Depending on color, White EGR/EGR Cooler, or Black Injector/s possibly.
Take it in, I don't think you'll have a problem!
