I have a vokera combi boiler and it keeps loosing pressure. We have to keep topping it up. What can I do until the engineer comes. As it is really cold and I need to keep my heating working.
I have the same problem. Does the flue look like there is a lot of steam?. If so, you need a new heat exchanger, part no. 1005245(about £140 for the part), sorry.

sounds like you have a leak somewhere or the blow off valve is seted open. you could get a 15mm push fit cap and stick i on the blow off pipe, but be careful your pressure doesnt rise over 3 bar.
