Welcome to the site! Is your engine burning or losing oil? The engine should not really smoke at idle. I would take it back to the dealer to have them check it out. There might be an update out there to fix it.
mine was doing it again yesterday while i was at the dealer and he said that it was just unburned fuel because of no load on the motor
Maybe something is hangin up with your EGR?Have a similar issue---at about 4000 miles my lbz seemed to loose some power--I noticed it first when passing---it didn't put you back in the seat as it used to---took it to the dealer and he said nothing was wrong--then noticed the smoke when idleing and also notice a kind of sharp burnt smell not a "sweet" diesel smell in the exhaust. finally it seemed that the mileage dropped a couple of mpg. Other than that, it runs good but just doesn't seem to have the zip it did have i now have 17000 miles and get about 11-16 mpg city/highway. Dealer says no codes, nothing wrong?? is my catalytic converter plugged up? would a "chip" help?
