Smoke from Exhaust

[masteroc]

Well, i did a search on the forums for smoke coming from the exhaust and found a thread or two suggesting that it may be from coolant leek from a turbo seal. The only problem is that i don't have a turbo (3.2 ftw). This car is a 2007 S-line Titanium 3.2 Quattro 6MT that i purchased new from the dealer (yes they had the car for over a year). The smoke that is coming from the exhaust is (as best i can tell) white. It seems to happen only under harder acceleration such as going up a hill or gunning it down a street. I am going to take it to the dealer on monday or tuesday, but i wanted your opinions first.

Thanks

is it thick or just wispy?

white smoke is normally coolant. hopefully not but it could be something simple. def bring it back and have the dealer check it bc that should not be happening

i had white smoke problem with my old car, ended up being something as serious as a headgasket.

definitely look into it.

there have been gasket problems on the coolant system for B7 A4's.

I had 2 replaced under warranty on my 2.0T.

Do you smell anything when you drive? Generally coolant is pretty potent and easy to smell... its a sweeter smell. Take it to your dealership.

It looks wispy to me. I am definitely going to take it in as soon as i can. I really hope its nothing too bad.

Thanks for the ideas/advice!

i also have 3.2. i had a blown valve seal that was leaking oil into the cylinders. mostly saw the smoke when starting car and under heavy acceleration. it was black though.

hope that's not the problem. good luck!

Black Smoke = Fuel Mixture (MAF/Injectors/FP)
Blue Smoke = Oil Burning (Valve Gaskets/Crank Vent Valve/etc)
White Smoke = Coolant (Head Gasket/Valley Pan/etc)

If you're seeing why you're seeing coolant. Get it checked and let the dealer work it out.

I agree 100%, im gonna take it to the dealer asap and let them handle it.
