Help identifying an engine pipe

[RichardMc]

Hello everyone.

I have an Audi Avant A6 C6 4F5 2.7 TDI from 2006 with a leak coming from a pipe that joins onto a short plastic tube just before the air intake of the turbo.

I don't know what the short plastic tube is, but I think it might be the crank case breather - am I right?

The tube and the plastic tube it connects to can be seen in this YouTube video at 3:15

I'm going to try to replace the pipe myself, so I need to know what it is to try and buy it online.
Any other advice on this leak would be appreciated.

Thanks for any help.

It isn't a leak as such, it is condensed oil vapour in the charge air system finding a way to bleed out and is quite normal.

Is the hose split, or does it just need a cable tie around where it fits onto the nipple?
