Hello, having just bought my A4 my sidelights and headlights are very yellow and dull so thought i would buy myself some white/blue sidelight leds and am going to get an hid ki for my headlights. Heres the problem when i fitted the led sidelights when i switch them on they come on for a few seconds then they flash on and off too my confusion. I have tried swaping them over and turning them round but to no ovale anyone know what the problem could be?? i tried the leds in my gti and they work fine so i know its not the leds so must be something to do my my car. Cheers for any help Chris.
