A3 2006 sportback small oil leak around sump

[rabbituk]

I had my car MOT'd recently and thankfully the guy doing it pointed out that I've got an oil leak .. I've been a bit slack about checking underneath. I had the car on the ramps at home today to see if I could understand where it was coming from. I think it is just the sump gasket however I also noticed oil on the pipe that goes from the turbo to the intercooler. Could that just be from the sump gasket? I think that's the case next to the sump but there was also a little bit of oil underneath the turbo. Have added some pics to show the leaks. Notice the burnt oil marks on the intercooler pipe. Oil was dripping off this before I wiped it off.
