hi I have a Polo 1.4 s petrol 16v 52 plate. The car struggles to start sometimes and when it finally does start it blows water and steam from the exhaust. It happens totally randomly it dosent matter if the engine is cold or warm. I have had a diagostics check done which shows no fault codes, changed spark plugs and checked for short circut no luck there. All the mechanics have told me thier could be numerous faults and by chance the day i gave the car to them it to them it started fine.Can anyone help

Sounds like a head gasket failure to me, loss of coolent mixing with fluids will be one of the reasons it chuffs out lots of smoke. It could be on the brink too hence why it works and doesn't
