I have a 2000,740i. the brake lights stays on constanly even when the car is turn off. after aweeks the brake lights are not working now.i change all the bulbs yet still not works.can someone tell what seems to be the problem with my electric.or were the brake relay,brake fuse and the light module please help have tired with people telling changees

If the brake lights stay on even if the car is turned off (or even if it is on) the first thing I would be checking is the brake pedal switch under the dash. Brake lights are activated when the brake pedal is depressed and comes off the switch or the return spring is broken or stretched not allowing it to fully return when foot is taken off the brake pedal.

it probably the idle position sensor...

Check the brake light switch. It is located up under the drivers side of the dash. It is either stuck on or it is out of adjustment.

Depends on car. But pretty much the same for most. The brake light can come on if the fluid is low in the master cylinder. Either from a leak or you need to change brakes. or the emergency brake switch is bad.

check the brake reservoir, if low put brake fluid. check brake pressure in the braking system. bleed the brake lines.

bad earth to lamp clusters usually when tow bar electrics fitted - or chaffed wired in lamp feed

the plastic round stopper most probably broke that is were the stoplight switch sits when not depressed easy fix find a washer small enough to block the hole were the original plastic stopper was making sure the washer aligns to the brake light switch and secure washer w/ zipties hope this helps.

its your blinker box.. all major lights run through there

i would check yor brake light switch make sure its adjusted correctly whitch will be located behind your brake pedal remove it press the button in and out your brake lights should turn on and off if this dont happen i would try a new switch as it sounds to me like the switch is sending a constan 12 v feed to brake lights

try changing your pads all round as they have sensors for each set of pads or just try and get a set of sensors
