The cossie one will always be a problem as your pads don't have wear sensors, you can use some resistors to make it go out as normal if you so wish though.
check all the sensors plugged obviously though?

The lights have always had a mind of their own, they can go for months without coming on, then be on for a week or so, then nothing. I'm on my 3rd ECU now as well.
With the resistors, do you know what rating I'd need?
