Water and vapor (steam) coming from the tail pipe is normal and will stop after a few miles when everything is hot. That is one of the reasons exhausts need replacing as they rot with rust and is more evident on cars that only do low mileage as the exhaust does not get hot enough to boil off the water and it sits in the pipe slowly rusting it away. What you see as smoke is probably steam and is more evident on cold mornings. If the car is not using oil then I wouldn't worry.
Regarding 2001 audi a6 quattro 2.7t....i was driving to work the car was fine then white smoke starting coming from under the hood and tail pipe. i stopped veilce and alot of oil was dripping from front of car. I towed it home and i looked under the hood and there was oil from valve cover gasket. i let the car sit for a few days, had it running again for a good hour and no white smoke was coming out. I removed the valve cover and gaskets are all bad. i want to know can the valve cover gasket leak cause the white smoke to come from exhaust pipe?
smoking from where?, front of car, middle or tail pipe.
is this your first car, or first car and first winter (white steam?)
there are 3 kinds of smoke
black , carb flooding (ask why)
white, oil, burning, take for ever to go away
white steam, goes away fast and smells like Antifreeze, sweet and nasty.
and all carbs smoke black in the tail pipe end, when cold, unless
you very carefully tune the choke plate.
so do tell? what?
if its happening during non cold weather then you may have a head gasket going bad and need replacement.you can have a combustion chamber test and a co test done on the cooling system to see if anything shows.be aware that may not show a problem depending on how early on the gasket is in deterioration.have you had to add coolant to the system or have recently noticed the level going down in the overflow bottle or rad.this is another way of showing a possible head gasket problem.white smoke indicates the burning of coolant.
White smoke continuously blowing out from the tail pipe ? If it is only at the cold position it is normal, if it is always coming out it means oil consumed & compression is week. spark plug frequently needed ? If plug frequently shorted u need to overhaul or need to add oil treatment for increase viscosity.
Its perfectly normal.Hot exhaust gases mixing with cold air and by products of the combustion process create the watery substance that you see spit out .Dual fuel (LPG,Hydrogen etc) vehicles do this a lot more noticably.By products of the combustion process are various but water vapour is one of them.Alot of heat is generated by the exhaust so watching a car driving in very cold conditions you can see this effect more clearly
