2555 white smoke

I just got my 2555 back from the dealer today after its 50 hour service. I moved some gravel, dirt and did some leveling with it. Nothing heavy. I noticed it would occasionally blow some white smoke. It didn't do that before. Any idea what that might be? The engine seems to be running fine.

Are they small puffs of white smoke when the engine is running at about 15 hundred RPM? Mine did the same thing when the weather was getting cold. I had the dealer do an ECU software update and it stopped puffing smoke.

A series of small puffs but my engine speed was 2000 or above. Also today was unseasonably warm around 70 F. The dealer had some sensor on the fuel line leak when he changed the fuel filter and had to order one. Could it be air or water in the fuel line?

White smoke on a diesel means incomplete combustion, causes are numerous, air leak, water, sensor that is sending false data to the ECM and so on.
