I have a Vaillant turbomax VUW 242E?

I have a valliant turbomax vuw 242e... The problem is that the pressure is reaching 3 bar.... I have tried bleeding water out of the radiators , this causs it to drop but it the climbes again.. could it be water in the expansion vessell?

Check your expansion vessel, try turning your cold water inlet valve off - see if it rises then, if yes then there is a leak on the domestic heat exchanger, normally if this is the case then the pressure would continue to rise all the time.

Thanks... I have checked the loop and it isnt drawing any water into the boiler.

First I would disconnect the filling loop in case it is continuously allowing fresh water into the boiler.
