Unhappy 1.75tbi Brera - not holding boost at 1.2bar


Hoping for some help with this issue as my first post - Hope you all had a Merry Christmas and have a Happy New Year.
I have a 1.75tbi Brera with only 29,000kms and it is not holding boost above 1.2bar. It is not a problem at heavy acceleration from stop or with high revs as the boost of the turbo is always lower then, but if you accelerate from low revs in any gear and the boost gets to 1.2bar the car lurches back and the boost drops and go back up again until 1.2bar and then does it again. It is really disconcerting. I have read the threads from JTDM owners on turbo problems around 1.2 bar - but am wondering if others have experienced the problem with the petrol 1.75tbi version or if others also have had this? Any ideas

thanks so much:
