Hi guys, newb to the forum - I am experiencing exactly the same symptoms as you have been coogsyrsv... I'm somewhat comforted in the knowledge I have a little more idea as to the 'possible' cause of this god awful creaking underneath my A4 Avant, and the 'clunking' you describe I noticed when I last visited the Isle of Wight 6 months ago (some rough old country roads).

I'll try and get this addressed relatively soon'sh, but do you chaps have any idea if this could be causing the car any further damage.

Thanks in advance
