1.8t steam / white smoke

[olibb]

Hello guys

I have just brought a 1.8t - and im just checking a few things.

In the morning i see a little white smoke / steam from the exhaust (it disperses quick and doesnt smell of anything).

I assume this is normal due to the cold weather etc (and from what i gather when a petrol car burns it produces water vapour).

But once ive drove 10 miles to work so the car is fully warmed up - i still see a little when sat in traffic or stationary?

So is this still normal for a petrol turbo?

The car does not seem to be losing any coolant or oil - also doesnt from what i can see smoke when driving atall.

I followed an S4 the other day off the motorway (so i assume his car was fully warm) and his did the same?

The only thing i can think to check if it is not normal is the PVC lines and valve?

Any help would be great.

petrol cars with catalysts will develop steam/water from exhaust

even once they are warmed up to needle pointing to 90oc?

Yerp. Sounds normal to me.

Are other cars in your street making steam too?

A 1.8t should be fully warmed up a good bit before 10 miles comes around on the clock. If you did have a cylinder head problem the coolant system can get over pressurised. Usually when you open the expansion tank you'll get a slight released of pressure release but if the head is leaking in to the system it can be more extreme. Care should be taken when checking for this phenomenon, a large heavy rag placed over the expansion tank cap when loosening it. From your description I concur with the other members opinion that the water vapour level from the exhaust is normal.
