Okay I know there are other blown turbo threads but mine is different, I think...

The sound on my B5 S4 is sort of like the turbo whine. Its the worst when the car is cold or I have not driven it in a few days. But after the engine warms up it seems to go away. So could it be something else?

Thanks for any input you may have!

 

That's how my whine started then it turned into a louder whine then a pop and smoke out the exhaust. Sorry, it does not look (sound) good.

 

I am not disagreeing but is there any other opinions or anything else it could be like a boost leak or something?

It only happens at really low boost pressure too.

 

check your skid plate and see if there is any oil on it.

 

And if there is?

 

if there is an excessive amount then you probably have one or two blown turbos.
