BMW 320D 2001 electrical fault
same car, indicators flash rapidly as if a bulb is out, when brake pedal is applied and realeased lights revert to normal flash rate, must be to do with brake light going on load.
Heres the crazy bit, put on the side lights and the offside front does not come on but the indicator illuminates and does not flash, the rear indicator is not illuminated, all tail lights normal. My dashboard is indicating a bulb failure offside front.
