Check the trunk light, the hood light (underneath the hood), the glove compartment light, fog lights. If these are all OK you may have the "rear fog light" burned out. German cars, in the rear right side, use a brightlight which matches that of the brakes willalways be on when fog lights are on, this bulb requires this extra step to notice - remove and manually/visually check all right side rear bulbs -since the left side will not light, you will not notice it during a normal check. If not, disconnect the battery, wait 10 minutes and reconnect, this will reset the computer, have the radio anti theft code handy because it too will reset. If this still does not work, there is a short in the electrical system.
