| Does your exhaust have a sweet smell to it? My guess is your egr may be leaking a touch of coolant into your exhaust. Mine did it along with many others. Mine would haze a touch of white and if i gave it some rpm's it would blow a bunch until all the coolant got burnt up. |

| Mine smoked when it was cold. Or if I had shitty fuel.  checking balance rates. Get your return rates checked. need a tech 2 or pull the injectors and send them out.

| Diesels will puff white smoke in cold weather AND when the engine is cold. Does the smoke go away as the engine warms up?

I agree on the need to check return rates. Just as an aside, fuel return rates can't be checked with a Tech 2 since it's a physical test. Only way is to pull the return lines and measure at home or send them out to be tested.
