A3 Quattro 1.8t
basicaly when I brake, a loud annoying beep sounds and displays a "bulb out" symbol on the dash the rear de-mister flashes on when the brakes are pressed, also rear wiper don't work it's temperamental, if you open up the boot with the headlamps on, the rear boot interior lights flicker and a ticking noise comes from a black box located near the 6 cd changer and bass box.
any ideas ? All bulbs work fine also. It's making me veery annoyed and I may sell it as this beep drives me crazy.
