Since diesels run cooler than gassers... extended idling does not warm up the motor enough and I have found not worth the EGR potential issues. Driving slowly will warm it up quicker and reduce wet-stacking and EGR issues.
I let it idle for 30 seconds to 1 minute (any weather) and drive slowly out of my driveway and neighborhood. I also believe it depends on what kind of oil one is using (the poster did not state when he asked the question). If using 15W-40, this is thicker than synthetic 5W-40 or 0W-40. The thinner oil will lubricate faster and flow through the high-pressure injectors easier... causing less noice and quicker lubrication.
I think that in cool weather, it depends on your oil and anywhere from 1 minute (I put on seat belt, adjust radio and other stuff while it warms up) to 2 minutes if using 15W-40. In the summer, I say 30 seconds regardless.
Good luck and enjoy.

I see no need for extended warm-up time.

10-15 seconds, then drive away........
too damned funny!
i have a 12% grade, up, as soon as i am out my driveway.
when it is under about 28* f outside, my truck WILL NOT go up that hill with less than 5 min idle time.... ideally, 10-15 mins if you wanna go faster than 2mph....
and dont turn on the main road where traffic (traffic, lol, the one car per five mins that drives by) is goin 40mph, or you could die.

What is the right way to drive these things. Some people say don't let them idle to warm up, others say let them idle to cool the turbo down, some people let them run all day and don't have any problems. I would think letting them idle for a 10mins to cool down the turbo and then shutting it down with all that unburnt fuel in the exhaust would be worse then letting it idle 10min to warm everything up. I can see idling it for 3-4mins after you just pulled the snot out of it before shutting it down, but normally you are not working the engine all that hard driving down the road empty then idling down your drive way into your gararge. I guess I will still let mine warm up when it is cold and risk replacing a egr valve before I would want to stick a engine in one. I kinda figured that is why ford has them idle up on there own when it does idle in cold weather or for a long time to prevent wetstacking. If they didn't want you to idle them they should not be putting that feature in. Besides it sounds like most people on this sight are disconnecting there egr valves anyways. I guess it is a personal opinion.
