Thanks Matty,
Mine's coming up to the 3 month service and although the compensator isn't too bad it's definitely noisier than when new.
I might just bite the bullet and get the new unit sooner rather than later.
Mine is going into B&C for the 3 month service in a couple of weeks time and I have asked them to change the noisy compensator. I expect the warranty to pick up the tab.
