Smokes alot..
I have a 06 A6 2LT with 4K miles on it. My problem is that when I start it when it has been sitting (cold), I can see a lot of white smoke when it is at idle (stop light). Now I know that when it is cold outside (as it has been) it is normal for cars to "smoke" for a bit. Maybe I am paranoid, but it seems like it smokes until the temp reaches about 200. Now, when I say it is cold outside, I guess that would be relative. I live in San Diego and it has been around 50-60 degrees. Also, I cannot really see much during the day, only at night when the smoke is lit up from the taillights. In addition, it is not black and it does not really smell like oil or gas. It is probably just vapor or something, but I would like to ask some of you guys with Corvette experience.
Oh, almost forgot. It is still totally stock
I want to get some Bullets, CAI, and a tune, but I am holding off just in case I have to take it to the dealer for this problem. I generally stay away from the dealer, but if it is warranty work I do not have much of a choice. I do not want to dealer to tell me that the tune messed up my AFR (possibly to lean..white smoke?) and that they will not honor the warranty.
Thank you in advance for any reply.

Fuel burns BLACK, oil burns WHITE. If it where oil smoke it would not dissipate much.... It would linger in the air and you would smell it.

Perhaps it is not smoke then. It does seem to dissipate quickly. So then is it normal for Corvettes. It just seems like my other cars do not do it for nearly as long.
Thanks again.

Oil burns bluish white. Water getting into the cylinder creates white smoke/steam.
The way you describe it it just sounds like normal water vapor (water is a normal by-product of combustion) especially if the temperatures are fairly cold. However, I'd have it checked just to be sure it's not something more serious.
Are you loosing any coolant?

Sounds normal. Too much fuel = black, oil = blueish white, water vapor = white. For every gallon of fuel you burn you create ~3/4 of gallon of water vapor out the exhaust. Most obvious when engine is cold.

Water Vapor
I don't live too far from you. For the first time this winter, it has been cold enough that on startup, the exhaust pipes are cold enough for the water to condense before it comes out to the atmosphere.
If the white "smoke" from a cold startup dissipates quickly in the atmosphere, it is water vapor. Normal byproduct of combustion. No problem. We don't usually see it in SoCal. Lloyd
