E220 CDI Coolant Leak
I think I have located a leak visually and have attached pictures of what I've spotted, although I'm not sure which part it is actually leaking from. Does anyone have a knowledge of the system that could point me in the right direction?
Many thanks.

it has an inlet and outlet connection for the coolant system at the bottom of it.
it cost £27.98 (plus VAT) from mercedes and is a VERY COMMON problem as pointed out by their parts guy.
Mine failed a few weeks ago also
