Nope but this is the kind of info I need
Any photos of it?
The 'odd' behavior is that the brake warning light comes on in the following circumstances.
When the car is cold, when you turn the headlights on... but you can turn the sidelights on without it bringing the brake warning light on.
The brake warning sensors have been hard-wired out so it's not that.
You can turn the headlights on once the car is warm (20 miles or so) and the warning light doesn't come on.
My thinking is that it's a bad earth and that the extra current draw on the circuit when the car is cold, when you first turn the headlights on and fire up the Xenons is enough to drop the current in the brake warning circuit and bring on the light... which then won't go off until you restart the car.
