Got my rear axle clicking finally sorted out today. Took it to a local garage where they replaced the spindle nuts regreased the axle and retorqued to 240.

The best thing about it was that the whole thing only cost me

 

No problem buy me a beer (or coffee!) next time you are at the office

 

I had a recall on this clicking lark from my dealer 2 weeks ago. Had it done free.
