One option from having to get your car up to running temp is see if your local autoparts store rents out a cooling system pressure tester with the correct adapter for VW. Now you can pressurize the system while the engine is cold to see if there is any slow leaks that the coolant could be evaporating while the engine is at running temp.
Is it low on coolant? does topping it off fix the problem?
Is it hotter when you are driving at speed, or just sitting at a light?
Definitely fix the radiator leak. You say it's leaking around the 'high pressure connection', do you mean where the bottom hose connects to the radiator? Since you just replaced the hose, double check that the clamp is tight enough.
Those plastic tanks (ends of the radiator) are notorious for cracking. Sometimes it can be an obvious crack, or just a small seeping crack that's hard to see, especially with the radiator in the car. If that's the case, a lot of times it makes more sense to get a new radiator rather than replace the tank. It's not that much more expensive, and sometimes it hard to get the tank to seal correctly without the right equipment.
It can also be hard to see the leak without a pressure test. I just realized how expensive the testers are, any good shop should have one, and they should test it for free if you want.
good luck!

TL/DR - Is it low? Fill it up. Fix the leak. Radiator shop.
Intake manifold gaskets are a very common failure on these engines, especially if the coolant has not been changed per the maintenance schedule during the lifetime of the truck.
If you take an inspection mirror (small mirror on a stick) and investigate the back of the engine above the bell housing you may be able to see liquid coolant; if so, replace the intake gasket.
If you cannot see liquid coolant, you can have your cooling system pressure tested to identify exactly where the leak is occurring. This is a quick easy test, generally less than $20 at any repair shop; or you can buy a pressure test tool set for around $60 and do it yourself.

You will either need to buy or rent a pressure tester similar to this
