Glad they have found it so quickly! Hopefully it should sort it out once and for all.
As far as mine goes a mate and I are going to have a go at the remaining 3 doors and look at the other one I attempted. Going to be removing the old foam seal from around the door panel and using some seal/mastic on a role. Its like a role of selotape sealant stuff, should be much neater and cleaner to use. After the panel has been fixed on I will be running a bead of clear silicon around the door panel before refitting the interior panel.
