05 A4

I have an oil leak somewhere in the area at the front of the turbo. The oil is only on the numerous hoses in front of the turbo, not the turbo itself. Currently I have cleaned everything off the best that I can to try and figure out where it is coming from. There is also oil in the line / duct between the turbo and the intercooler.
The car seams to be running fine and not burning any oil.
I am thinking it could be a bad bypass valve. I'm correct or am I missing something?
