| The car is a 1.8 petrol. 
 I noticed today quite visible smoke (whitish) coming out of the exhaust pipe even when the engine was idling.  Could this just be the cold weather and what else should I look for if it is something more serious ?

 Or perhaps it was just steam due to the cold weather.

 Assuming all else is starting/running OK.
