Re: Brake light went out, I replaced all the bulbs, but...
Hi, have you checked to see if the eye level brake light is working, other than that check the wiring harness for the boot/tail gate within the rubber corrugated trunking on the right hand side near the boot hinge as it is quite common for the wires to break wear they always flex and check the multiplug on the back of the rear light unit as the earth terminal may have burned out, hope this helps, regards mark.

there area magnitude of things that can be the issue here. I wil take a chance here and say that there is an issue with a couple of sensors. This situation involves 1. The brake light sensor (which indicates that i brake light bulb is faulty) 2. The Tire pressure sensor (which is the tire pressure) and 3. ABS sensor ( Which i would associate it with a wheel speed sensor)
You should check the tire pressure, and correct it. Check the bulbs on your brake light and replace as necessary. Then check for a torn or broken ABS sensor, which are located on each wheel,
Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.
water in the rear brake light assemblies. common problem. remove the brake lite assembly------very very easy thing to do. there are three nuts holding it in from inside the trunk. once they're off the whole assembly just pops out. then it can be cleaned. usually the rubber gasket around the assembly leaks water into the lights and messes up the contacts where the bulbs screw into the circuit board.
The problem is electrical connection to the light bulbs. You need to open the fusebox in the bonnet and let the motor electrician check which one of them is blown. This is not a major issue except for driving especially at night as long as the brake itself is working fine. You might just need to use your hand as a "traficator" meantime.
I Just had the same problem. I found that the bulb socket was inserted in such a way as to cause a short which blows fuse 46 when you press the brake pedal. I also had some bulbs which didn't fit properly. I hope this helps someone out. Also when Fuse 46 blows, you can't start the car till you replace the fuse.
For those of you who don't know where the fuse panel is its on the left "driver's side of American BMW's under the hood nearest the windshield cover by a rectangular black plastic box. It snaps open from the front side.
I took out the whole light assembly and cleaned it and replace all the mismatched bulbs with the correct ones, to be sure I fixed my problem for good. Check control now reads "ok"
All this refers to when you press the pedal all the brake lights stop working and you control center says brake circuit failure.
