Coolant low warning - hose

Coolant low warning - hose
So today the first issue with the Jaguar, during a trip and when almost home, the warning light from low coolant went on.
Stopped the car and opened the hood to try to find what happened and everything splashed with pink coolant and a hose broken (the only one i could find):
Filled the expansion tank with engine running to check if was the leaking point but nothing come out from there.
Anyone knows what could possible make this hose to crack completely and if is this the reason of the leak? Is this common? Couldn't find any detail or diagram about it.
Regards,
Bruno

I have looked in my engine bay and through the Workshop Manual and I can't tell what system that hose/pipe is part of.
It doesn't appear to be a coolant hose as it is not shown at all on the (comprehensive) coolant component diagram in the Workshop Manual.
I have just come in from a run in the car and while the coolant system hoses and pipes are hot or at least warm that particular hose is barely warm at all.
Bottom line - I don't know what that hose is for but I'm fairly sure it is not a coolant hose and my best guess is that it is a vacuum hose of some sort.
But if it is not a coolant hose where did all the coolant leak from?
The plot thickens!

I am already expecting the worst, Jaguar might only have time to check the car next week so i am here dying of anxiety and no clue.
Looks like some oil too(?)

Exactly, something fishy, doesn't make any sense, asked them to check! Let's hope is just due engine vibration, i always drive a bit too fast.

CJSJAG,
The part in question is the purge valve P/N AJ814246 and retails for about 160.00. The other line that is undamaged wraps around the insulation/rubber piece is a low-pressure fuel line. Due to the pressure of coolant when blowing out of a hot engine makes it very difficult to tell by the pictures. I would imagine its probably the crossover in the back of the engine, upper radiator hose, or something around the thermostat area.

The R have now about 85 kkm or 53k miles and really well maintained, but nowadays i almost don't drive it which perhaps isn't so good for rubbers (?). This was the first issue and let's hope it stop here

I was about to say that it was good of you to admit that you missed his details due to your advanced age and failing eyesight but then I guessed you were possibly talking about the car!
