Red warning light under air vent bottom right Mk2 Stag

[bonnietiler750]

Now since I changed my discs and nothing else this red light, bottom right under air-vent is illuminated
What does it warn of?
I didn't think I'd done anything to cause it grief
Please advise

Oops. The shuttle in the twin curcuit braking system has been activated and moved to one side. Might have been when you pushed the pistons in the calipers back for the new pads. Need to reset it and check that both curcuits are fluid tight and dont need bleeding. If you have the ROM it tells you what you need to know.
