E-Class - Coolant Leak?

[aquiss]

Just got a knock on my door by my neighbours who spotted liquid under my car. Opening the engine, it appears I can see blue liquid sitting on silver box, just behind the radiator fan.

I'm no expert, but I think the hose just above the silver unit goes to the radiator.

I have attached a picture for the experts to get a better idea.

Kind Regards

Oh well, I called Mercedes Roadside assistance this morning at 8.30am, within 90 mins, the car was collected and at dealership where it was confirmed as a major coolant leak, but presently not 100% sure where its coming from

The car currently i'm told has had its front bumper and radiator removed. As it's under warranty, they are replacing a load of hoses and the silver unit, which I'm told controls the coolant to various systems.

Replacement hire car is a new C-Class, though I must be a little spolit with my E-Classs, as I can't say that I've warmed to the C-Class SE spec at all :/
