ive got an audi, 122k miles only had 2 months, the problem ive got is its leaking oil out of the bottom intercooler pipe and theres a noise when i de eccelerate from about 3k revs? any thoughts?

been told its a turbo problem so brought a new turbo but its not been fitted yet, im asking because if its not that then ive wasted my money and time.. so im on here getting more thoughts on the matter.

thanks
