New 308 knocking

[Guy3326]

Hi , Iv got a 2016 308 SW 1.6hdi ,
That's got a knocking noise coming from the front suspension area. Sounds like a drop link but its not. Has anyone had any experience with these or does any one work within Peugeot that can have a look and see if there's any bulletins for knocking on the front.
I'm thinking possible top mounts but don't want guess at them just for the sake of it.

Thank you
