Arnage T - Knocking noise

[dazzalse]

We have a late Arnage T (2009) which has only covered 10,000 miles from new, the last few times we have used the car it seems to have developed a intermittent knocking noise from the NSF suspension, almost like a metallic thud if something is loose, she is off for her annual service in a few weeks but wondered if anyone had any ideas or common problems that affect these?
