smartshield indicators flashing while driving

[waymax]

Have a strange problem which started today. While I was cleaning the engine bay with a high pressure cleaner making sure not to hit the electrics after a radiator hose burst on myxr8 series 3 , the indicators started flashing for not apparent reason. I took it for a drive and they kept flashing. The only time they stop is when you lock it. Got me buggered any ideas?
