Default Smoke at high acceleration..

I have a 2007 B7 2.0T Quattro that seems to run fine. I was driving down the street and went to pass someone, gunned it, when it shifted while at high rpm (7000) I got a huge cloud of smoke out the back.. Looked like a James Bond style smoke screen behind me... I noticed no change in the engine, no loss of power, no shaking, etc.. Any idea what would cause this?

I'm a bit concerned...

Did you get a CEL ? Also do you still have the original PCV . You may have just ruptured the diaphragm. Get it checked out.

No CEL, don't know about the PCV. I just bought this used (33,000 miles) three months ago.. I am trying to get a service appt ASAP

I was looking around the web, and found that apparently *many* people have this issue, or somthing like it wrt the engine just drinking oil..

It's prob nothing, there are a few reasons why your car is smoking at high revs:

Turbo cars tend to run rich at higher RPM to prevent detonation, so black smoke is the unused gas burnt.

More likely is that your turbo is working overtime at high RPM, and since the turbo is oil-cooled, some engine oil is burnt in the turbo, thus the blue smoke.

Either way, it's not a big deal so long you don't do it often. The same thing happened on my DSM, Evo and B5 before, just remember to cool off the turbo after spirited driving.

@Modena -- It was white/blue
@yycools -- I hope so ;-) I just notice that this seems to be an issue with the B7 models with the 2.0T...

Ever hear of blowing the smoke out once in a while. It will smoke more up top in the RPM's. Does it more when the cat is removed and chipped.

The color of smoke is usually high RPM emmisions gas or oil being burt. I'm sure you have put in a quart or so inbetween changes as these cars are know for eating some oil. Thats where it goes.

burning that oil!!! Long term I have heard that all sorts of expensive fixes will be needed do to the oil consumption. Sad but my car does the exact same thing. I was also told that if you live in a state with stricter emissions you may have trouble passing or need costly repairs to the cat converter.
