2013 JCW Mini - Strange turbo related problem

[Dalmahoy]

Good lady of mine bought a 2013 JCW Mini from our local Mini dealer approx 3 months ago.
On getting the car home - first thing was to open the bonnet and see what's inside.
Noticed the intake hose from the air filter to the turbo had come loose at the turbo.
Just a hose clip so refitted the thing thinking that would be it.
Couple of times after that - again noticed the intake had come off.
Booked the car in for its first service and mentioned this to the dealer. They checked it over and mentioned it all looking okay.
Since then - I have refitted it another couple of times.
Any ideas what's happening?
Cheers

Here's what I have been finding:-



Clean everything up and see how long it holds together for this time:-

After cleaning all the parts using panel wipe - I noticed the green silicon bush went slightly 'tacky'.
And after refitting everything, the hose has went from popping off every couple of days to still remaining fitted a fortnight later.
Admit I can live with that so I'll see how long this 'fix' works.
