2000 BMW 7 Series

On certain 323I, 328I, 528I, 528IT, 540I, 540IT, 740I, 740IL, 750IL and M5 vehicles, the brake light switch capacitor housing may be cracked and in high humidity conditions the capacitor and switch housing could become overheated and deformed.  As a result, a short circuit or an open circuit could occur in the switch.  This could cause the switch to remain either in the "brake lamps off" position or the "brake lamps on" position.  If the switch remains in the "off" position, the brake lamps will be rendered inoperative.  Conversely, if the switch remains in the "on" position, the brake lamps will be continuously illuminated when the ignition switch is in the "on" position.  Correction:  Brake lamp switch will be replaced with an improved switch.
