I'm pretty certain that all the stuff was dry when I put it in. I'll
try and work out if the damp/wet bits are above anything obvious.

I'm assuming a DPM is the same speak as a vapour barrier? I'm loath to
do this as it would entail lifting ALL the insulation (Pink Panther +

No need to lift the original.

Just put a seal between it and the other..

The original will stay warm enough not to condense..
