Reading this thread:
http://www.volvoforums.org.uk/showthread.php?t=125920 prompted me to search for this one that Mike started. It was intended to become a guide with folks adding there findings as and when to provide a mass of information about the dreaded 'tin worm'. One from which we can all benefit.
So here it is 'bumped'. PLEASE do add to it. I'll give it a couple of days and then will ask for it to be added to 'articles' with a link back to this 'original thread' like the others .
Thanks for reading
