Well, went to start the 7 and with the ignition on there was no orange light, great news. So, started it up, and still the light is off :) moved the car into the sunshine (I know, in Scotland!, in March!). Then noticed the light was dimly glowing and over a couple of minutes brightened up a bit more. Taken the decision to warm the car up completely. Fan kicked in when warmed up and the light is dimmer but not out yet. I have left the bonnet and engine off now and see if it dries out. I will check and give and update in an hour or so. Looking good so far. Phil
