I think there is a pump which can leak which can be accessed through the wheel arch.

Pretty sure the resevoirs come in two parts

Are you sure it's not the aux rad or condensation from the air con. Guessing you've checked the obvious...screen wash level!?

Leak is def from the washer res as can see it coming straight out when you top up plus warning light on dash
Will i just need to replace a seal o ring as pumps are working just dont hold fluid.

I replaced a bunch of grommets around the washer reservoir, from my notes: "Replaced windshield pump grommet, sensor grommet, 2nd overflow tube grommet. Replaced several wheel arch liner fasteners and nuts. No leaks! Headlight pump grommet about the only one not changed". All were accessed by removing the wheel arch liner.
