Have topped up the water on my combi boiler to approx 3.5 bar.Everything seems to be working ok, but can this cause a problem or will the pressure readjust to he correct level?

Thanks Ste for the reply.However I should have said this was my daughters boiler,and I will not be able to get to drain the water off until I next visit her which may be a few days.So will this be ok until then?
What if any damage can it cause if the pressure is higher than 1.5 barre.
thanks

just drain some out through a radiator bleed screw until around 1.5 bar when system is cold.
