Guys there is a black puff of smoke or blue. I kno its oil. Its under hard acceleration only thou. So why would it only smoke for a second under hard acceleration. Thanx

 

my car will blow black smoke out of the exhaust when i really romp on it going down the highway(going 70 and it shifts down to 2nd(A4) and goes to about 4800 rpm) This is what my friend told me after he followed me one time. my friend's t/a does the same thing. so, i don't know what this is, but your not the only one that this happens to. (i guess this is what your are talking about?)

 

Black = running rich, not harmful at all.
Blue = Burning oil, not good at all.

 

It is normal as long as it clears up after you have stayed in the throttle for awhile,mine does the same thing.

 

how many miles are on the motor? could be blow by.....

 

110 k i guess its happening to everyone not bad eh? good lol thanx
