After rereading your post again and trying to work out it's exact location,am I right in thinking the dosing pump must be near enough above the diesel cooler

No, the diesel cooler is much further back, behind the rear wheel, the dosing pump is in front of the rear wheel.

Turning the FBH off stopping the leak, makes no sense at all - if the leak is from the cooler area. Might it be instead dripping down the side of the fuel tank?

The Fuel supply pipe for the FBH enters the tank via a removable panel on top of the tank. That panel is under a second (body sealing) panel on the off side, under the rear seat squab.

The dosing pump feed pipe runs from the top of the tank, then down to the pump. If that pipe were damaged, it would continue to syphon fuel out of the tank, until the tank level fell to near zero. Turning the FBH off, would not stop it, only a dosing pump leak or pipe leak forward of the dosing pump would be stopped by turning it off.

The fuel cooler has been known to suffer leaks - I had one. It turned out to be a leaking connection onto the cooler. Remaking the connection cured it.

That latter might be your problem and turning the FBH off curing it, might have been coincidental.

Point is - decide whether the leak is ahead of the rear wheel or behind it, for certain.

I'd be tempted to lift the rear seat base, remove the offside tank panel and check for leaks around the module top. The seals are a known leak point and it is quick and easy enough to do.
