hi Everyone,
My Audi has developed a problem with white smoke. It's not noticeable when engine cold/idling, but when it warms up and under acceleration it produces excessive white smoke, not stupid amounts that would blind people behind but enough to notice.

It's not head gasket or anything to do water getting into the cylinders, the coolant level stays the same and the car dos not overheat.

I have also noticed that there is slightly excessive hissing noise when accelerating. I think that there's probably a leak in one of the rubber air intake pipes to do with the turbo.

My question is would that potentially cause the white smoke? Or is my problem more likely to do with injectors, or piston pressure?

thank you
