mine too now! just drove home with the green indicator LED constantly on, and no indicators or hazards flashing.
went to garage on way home and found water around the hazard flasher. I assume after reading above and Matey Matey it sounds as if its coming in around the bonnet release cable grommet.
Will seal this up at weekend in the daylight. In the mean time can I squirt WD40 over fusebox and the relays to drive the water out??
already blew most of it with an air line so we are working agin for now!
