white smoke on start up

[shailesh]

i'm not sure about this but everytime i start my car up in the morning i notice some white smoke puffing out.not sure what the problem could be
but only noticed it now recently.i have checked my water and oil levels
and all seems fine.

what could the problem be ?

Does the smoke appear immediately on start up or after the car has been idling for a couple of seconds?
Exhaust vapour can also appear as "white smoke" which i suspect may be the case. If so, this is perfectly normal.

That is an easy answer.

You have a blown thingymagig on the left hand side of the rear tyre valve.....OR as is more commonly known....condensation out of the exhaust

My E46 also does this on the first start especially on colder months or on rainy days . In summer there is nothing :=):

my car only when temps dropped below 5 would smoke like a steam train in the mornings,the whole car was covered in white smoke once the exhaust tunnel had warmed up,

was quite a sight

was even funnier when the 330d next to me was doing the same thing, i can only imagine what people would think seeing that

Had the issue, but my car did it all the time hot or cold, whenever I start up or get on the throttle


turned out to be valve stem seals - hopefully not the case for you
