Those lights rarely burn out. More likely the switch on the brake handle came unplugged. Try grounding the wire from the ebarke switch with the key on.



For the mirrors, I would pull up the control panel and probe for power. Trace the power through the mirror sekection switch, etc.

You have a brake light switch attached to your brake pedal,may be loose or bad.Read what it says,if bad light will stay on,easy to replace,just disconnect electrical connector,then unscrew nut,then remove,the end piece clicks on and off,I have a 85 Nissan 720 truck,have replaced mine before years ago.

You can not simply reset the light, you have to actually replace the brake sensor wire that connects to the rear brakes. This is a sensor that is worn through, when the brakes get low, the sensor rubs the rotor and breaks the connection, turning on the light. You need to get a new sensor from a dealer and replace the brakes and sensor together to get the light off.

After replacing the wire as stated do the following to reset the light and mileage countdown timer.

To enter this mode, with ignition on, hold the odo reset button (located on the left side of the instrument panel under the tach) for about 10 seconds.

The center of the info display will change to "service". It will have an icon for which service feature and the miles/date left until service is required. These icons are the same as displayed on the I-drive service screen. So, you can go through the Idrive service screen to get familiar with the icons prior to doing this.

Once in this mode, push the reset button to cycle through the various service items.

To reset a service item that is displayed, hold the reset button. I don't remember how long, but the display will change to a reset mode. You must release the button once it enters this reset mode. Then you will need to confirm the reset by pressing the reset button again.

The reset service interval will then be changed.

You can continue pressing the reset button to scroll through the other icons.

I think to exit, simply shut off the ignition.

I think there is a brake wear sensor that will need replacing when you replace the brake pads.

to reset light brake sensor must have been replace close door turn key on but dont start car when time is displayed on instrument cluster press and hold button on left side of cluster a orange triangle will appear keep holding next service function will be displayed release button to scroll through services that can be reset just push button again without holding when rear brakes are displayed on cluster press and hold button again the message reset with a question mark will come up release button and then press and hold again and light will reset

The green bar is the service indicator bar. The bar shoulld decrease every 1500/2000 km to indicate still how far you can drive before the next service. It will evetually change to yellow and then red. This means the service is overdue. When my 1995 318 went for a service the dealer reset the indicators to full green bars. A week later the bar was in the red. Some computers are prone to this fault due to low ore loss of battery power. Just make sure the physical km of your inspection is still maintained. BMW SERVICE RESET Take a small wire, paperclip, or elect wire and bend like a horseshoe. No light or equipment necessary Open the diagnostic data port, the one were the little pacman centre is located. Turn the ignition to position 2, don?t start. Connect pin7 always first and then pin 19. Hold for 4 seconds. Remove wire and settings will be reset. Warning if you hold the wire longer than 10 seconds you may reset inspection intervals 1 and 2. I?ve done this twice and it definitely work on my E36

you can remove the cluster and buy the bulb separate as far as the brake light it is either the float is bad in the master cyl. or you have low frt brake pads

on the rotors you probably noticed two lines one for the brakes and the other is your traction control magnet which picks up a signal to tell the computer to control the braking system when the wheel locks up in hard braking, you either damaged the magnet or it picked up some metal shaving while replacing the brake pads
