Hi,
I have a 98, V6, 2.5 TDi A4 Quattro. Recently I have been getting smoke from my exhaust. Thought it was burning oil, but its not. The engine runs sweet as a nut. There was a chip in it when I got it a while ago.
The smoke is not affecting performance. I have heard it may be using more diesel than normal, but it seems not.
Anyone out there got any ideas ?

Thanks.

 

it is white smoke or black?

 

Hi,
The smoke is white, its not oil, I have been keeping a check on that. no affect either on acceleration, ticks over well also.

 

the oil smoke is white i think your turbo is going tu die.black smoke is good white is bad!!!your ring in the turbo is broken !!!diesel engins is not god sign white smoke.. you kann ask another. i have ol so diesel audi!!!

 

what chip you hawe ecu flash or you hawe outside chip?when diesel is not burndt it is black smoke,and oil smoke is white,blu.

 

hi guys,
Thanks for your help. I had not thought about the turbo, you may well be right, the thing had a chip in it when I got the car, a while back, it may have run its time. I will get it checked. Thanks again.
