I've got a Baxi 105e combi instant noticed the boiler pressure had gone to 3 bar , the relief valve is doing its job and the filling loop is uncoupled any ideas?

I'm sorry I don't think so.....if water is exiting the system via the pressure release valve, and the filling loop is disconnected, the water incoming has got to come from somewhere - you get my drift?
The diverter valve just allows you to have a choice between CH or DHW, and the expansion vessel allows for hot water expansion - as it is a sealed system.

Make sure you order the one for the instant and not just the 105e they are different costs around £60
