You can have an air leak and your gauge wont even pick it up because your turbo can supply enough air. A vaccum leak on the lines going to the actuator will cause the boost to increase.
Its either a faulty gauge or your actuator is damaged.

the way I understand it is if there is a leak under boost, the turbo might boost more because there is air escaping.....but that does not show on your boost guage
Vacuum leak would be visisble on your guage, unless it is a very little leak and that would not cause a 0.3 bar increase would it.....

the vacuum hose between compressor and actuator seems fine, although, before I could take it off completly and the boost would not increase at all(that is why I stated I need a new turbo), why now suddenly increase....
I can not exclude the guage faulting, but why now suddenly, it was fine before.....and why as I said this all happened directly after I put in fuel on that spicific day and time....
