Strange though, as surely the filter should block any noise from making it onto the DSL frequencies.  I wonder if it was somehow creating a short circuit?

It's difficult to say with any degree of certainty. But, as neil has now replaced the component and the fault is no longer present, the result is good enough for me.  :)

Those two plots are indicative of one (or more) defective joint(s). The problem is finding where it is (or they are) and then making a lasting fix.
