if it is a disco11 and the carpet(or rather the sponge underneath is sopping wet)the carpet can appear to dry out by the way,there was a panel on my disco which is in the bulkhead underneath the big plastic cover on the near side which was not tightened up properly from manufacture, it is about 8 inches by 3 inches and looks like it should of been bolted on the outside rather than being on the inside,this is where water came in when it rained i loosened the captive bolts a little and bunged some mastic in(sorted)
