Need some help here please! My brother owns a 320d M Sport 2009 LCI and has developed a crazy fault, what happens is soon as you turn the lights on, the dash goes crazy with warning lights, including Airbag, Service, DCT, ABS, rev counter goes up and down, you name it, when you turn the lights off the car goes back to normal. Checked all the lights and all bulbs look fine.
Does any one know whats happening, below is link to a youtube video I have uploaded for the fault.
