Hello all,
Something happened with my 1.9D when I'll start at the morning. The FIRST-SECOND minute it produces white smoke and attempt to stop if I keep the pedal on idle... but that is only when I'll cold start it.... after a minute or two everything becomes normal
any idea?

They've checked them... all operational... they suggested adjustment of the valves, but I don't think so, because it works normally when it hit 70C, or 200meters driving

If this is new and you are sure you haven't noticed it before or it has significantly increased it can be water getting into the cylinders from the coolant and the beginning of head gasket failure. Check your coolant level, check the coolant header for oil residue, check the oil filler for mayonaise like substance though note that this mayonaise can also be caused by frequent very short journeys especially in cold and wet weather. Any of these other symptoms reinforce a probable head gasket failing.
Get a "sniff" test done. A garage can check the coolant for combustion gases.
Another cheap(ish) test is a compression test though few people have the tools to do this on a diesel engine.
Are you sure it is white and no blue tinge and does not smell of oil? If it is / does then it is oil burning.
If it is genuinely white and then it is back to either condensation burning off when cold or coolant / antifreeze (assuming you use antifreeze) burning off. Hold your hand very close to the exhaust any you will see steam or oil settle on your hand.
If it is genuinely white and smells quite sweet then it is probably coolant getting into the cylinders.
As Andy has said it could just be normal combustion gases. Complete combustion of diesel (a hydro / carbon) should primarily produce carbon dioxide CO2 and water H2O. When everything is completely cold the water is exactly that and you only see drips from the exhaust, as the engine starts to warm you get visible steam, when properly hot the steam is still coming from the exhaust but you don't see it.

Mine did this the other morning because I was half asleep and didn't notice the glow-plug light was one before turning the ignition all the way. Absolutely fine yesterday morning (left it a few seconds to let the plugs heat up). Probably just a bit of condensation in the system, especially if it stops after a couple of hundred metres. Does it still puff white if you drive a bit (say 500m), then stop and idle? If not, def condensation.
