Hi,
This was my experience with suspension noises that I finally got sorted after more than a year.
I totally feel ur pain as I spent so long researching what it could be but ultimately, each of our problems can be different.
Perseverence is the key here and even though the garage may tell you all is fine, if you know urself it's not then keep going back before the warranty expires.
Regarding the suspension noises, there is a TPI issued 15th April this year that involves dropping the wishbones and greasing the bushes with a more substansial grease. This cured my creaking, pattering and squeaking noises.
Regarding clunking, mine turned out to be caused by a broken bracket which holds the auxillary water pump in place at the front of the engine.
All this was finally sorted after being fobbed off for more than a year and lots of visits to the dealer.
Good Luck!
I hope this helps in some way.
