It might only be a weep...
I have to my disgrace been looking at the tide mark on the expansion bottle thinking it was the water level.
The is a bit of crust around one side of the radiator, which is quite new... Being OAT coolant, you don't get the old c
blue crustyness hence the dye idea.
I was looking at this type of thing (I have access to a good UV lamp)

What got me thinking about the coolant was a humid feeling in the car making me think about the heater matrix, but we have been on a camping holiday with lots of beach and wet towels and wetsuits in the car.
I need to do more research, but the car seems to have an electric heater, not sure if it is additional / Aux or if it has a traditional matrix too.
I thought we had a leak into the underside of my Wife's car - when I took the spare out (was having a tyre changed and taking the wheel to them rather than have them 'dugga -dugga' the wheelnuts) the wheel had a little rust and was damp underneath....... then I found the small folded umbrella which was still damp, and had somehow got under the boot liner into the spare wheel well
