Anyone have any advice on how to find the leak?

I'm still a newbie A8 owner and all was well until this morning when I had the dreaded flashing icons - this is what vag-com said:-

I tried clearing the codes but they all came back straight away.

I'm assuming that the over-temp is due to the compressor being taxed to overcome the leak - question is, how to trace the leak?
