Slow engine oil leak, possible source?

[Papagut]

Hi everyone, 

 

I have a slow oil leak happening at the far front drivers side of my 2004 Cayenne Turbo. I have it down to a fairly small area, but am not sure about the likely source as the whole area is a bit fouled up. Would you let me know what you think would be a likely source? I lose about 1 litre over maybe 6-9 months. 

 

First image is from inside the left wheel well looking forward, second and third images are from underneath the same location from different angles. 

 

Thanks, 

Mark

I had the same leak on my 05 TT.  Here's what I found and I made a DIY.  You might want to copy that title and hit search on the forum where I posted.  Hope this helps.
