Gilly,

I had something I had to attend tonight, so i only just managed to get underneath the M, with trusty light in hand.

Your Diagnosis was 100% correct , its a cracked weld on the Cat Chamber, so off the the Dealer I go, Wish me luck . I will let you know how I get on.

Once again, *Many* thanks for your assistance!!

David.
