There is away around this one live with the car telling u that the balb is out or two u need to fit a diode between the centre brake line to the left and one from the centre to the right and have a wire connecting between the two diodes that the controller picks up this stops the warning coming up, im sure that made no sence so il try and get a diagram up here so it makes sence.
Awesome - thanks for that.
I'm not much of an auto-sparky - but I'll take the comments along to the auto-electrician I'm seeing today and see how we get on.
Appreciate the help.
