Cdti overheating

Hi folks
Bit of an unusual one, my cdti is overheating!
I've replaced the top hose stat with a tested one.
Hot water didn't appear to moving through the rad, so took bottom hose off to backflush it, water came out the rad but nothing from the engine side?
Rad is running freely
With bottom hose off header tank is still full of water
Run engine with bottom hose still disconnected and got a good flow of water out of bleed point... Suggests water pump is still working well?

At a loss now as I know the rad is now empty but the header tank hadn't drained and still no water coming out the engine at the bottom metal pipe?

Temps are getting well above 115degrees, fan is coming on at 100 but there's no flow through the rad even though there's no restrictions so no CD water reentering the engine

How much is a Ztt worth as scrap?
