Unknown coolant pipe

[orkano]

I recently changed my slam panel on my mk5 gti and about a day later got a coolant leak from the radiator fan eating away on one of the coolant pipes. I've looked everywhere and cannot find a diagram relating to it or what part number it is in order to replace the pipe. The closest thing I have is a part number for an adapter, which is 323220, that connects 2 other pipes to it. In the picture, the faulty pipe is the one with the smaller diameter. Anyone know how I can find out what part number it is or what it is?

That's number on the connector isn't the part number but relates to the size of the 3 pipes, 32mm /32mm/ 20mm I believe.
Using the link that would mean the connector is item 10 so the pipe you need is the smaller one of those that attaches to this, probably item 4.
