Why's my boiler gone over-pressure?

First thought, air in system, though bleeding all the rads doesnt

Shouldn't produce any "air" at all after a system has been in use for a
while. Routine bleeding of radiators is indicative of either lack of a
inhibitor (thus the "air" is hydrogen from corrosion of the steel rads) or
there is fresh water being introduced on a regular basis.
Pressure now down to 2 bar when it is cool.
Pressure gauge was lying initially, did you give it a little tap?
