Brake light circuit means one of the brake lights is broken. Or it could be that the fuse got disconnected. Just get into the fusebox and move the fuses around. If that doesnt fix the problem then it is probably a brake light relay.

PS - manual wouldnt really tell you how to fix the problem, it will most likely direct you to a dealership.

Sounds like the brake light switch on the pedal, or you aren't using hte BMW branded bulbs. The copper based bulbs you buy at local parts stores can cause the LKM to freak out and trip a brake lt circuit error. Change to BMW bulbs in the tail lights and see if you get it then. If you still do, it's the brake light switch on the pedal.

Mein Auto: 1996 328i
Question

I had the brake light circuit warning come on last week while driving I have a 96 328i, 104,000 miles.) It did not come on the next time I started the car. When I took it to my mechanic, he said that it was a problem with my ABS sensor and the repair would be $1000, but he couldn't find anything wrong with the fuse or lights.

Are these things related?

It took me 7 minutes to change the ABS sensor. Find a new mechanic!

i am not sure if my problem is exactly the same, but it is similar. When I start my car, normally the brake light turns on until i push the pedal. The problem is when at night and my lights are on. Not right away, but after a while, maybe 15 minutes or more, the warning light comes on and it wont turn off until I restart my car. It is very inconsistent too. Oh yeah, my brake lights work fine.

Mein Auto: 325is
Mine is out

My brake light faliure just went crazy on the nav system. The middle lights work fine but the outer lights wont even turn on. I checked the fuses and they were all ok, and the brake pedal relay seems to be working. Any other ideas?

Brake light circuit

I have a 323i. The brake light circuit is flashing and both of my brake lights are out. I checked the one fuse that says brake light and it looks fine. Do you have any idea what I can check? Thanks

Talking new to BMW

I have a 1995 325is, I was getting the brake circuit warning on and off until I was told about the switch under the pedal. All I had to do was pull back the floor mat from under the pedal and I haven't gotten the warning again.

If you have one working brake light, then you obviously have a working brake light switch and power to the bulbs. Replace the two side bulbs. :duh:

Mein Auto: 530i 2002
My 2002 530i has some sort of brake light problems. I have replaced all lights with BMW lights. I have purchased a new battery from BMW. I have installed a brake light switch from BMW..HOWEVER, I dont know IF I installed it properly...Seems there is only one 4 pin plug side that connects to the car under the dash and steering wheel. I now can start the car. Before the car had power but would not start at all and showed no lights on the rear as if they were not being pressed at all. I think the new Switch solved that problem. The back brake lights behind driver side do come on but dont work as for a reverse light and a turn signal. Those are shot. The rear brake behind the passenger doesnt come on at all..No turn signal reverse lamp nothing. But, the head lights and front turn signals all work.

What could be causing this problem? Like I said Ive switched all bulbs to BMWs. New BMW battery. New BMW Brake Light Switch? Need to know if I attached it properly. Seems to work to allow the car to be started again. But, could I have missed something? Is there a second connection spot on that Switch? I see the metal clip to hold the new switch but cant get it to fit into position. And the actual new switch has a second half to it that the one that was attached did not have. ANd I cant find that second half anywhere near where the original switch was attached. So the New Brake Light Switch is ONLY attached with the 4 prong rectangle piece. The second half is hanging down above the under dash cover. Anyone have something similar to a 2002 530i? It has 102,000 miles on it and otherwise runs perfectly.

Welsome David. You have an E39 and are on the E34 forum. Not that we don't welcome non-E34'ers, but you may get better information on the E39 forum here:

If there is no problem with the brake light switch or the brake light fuse,then you should probably check the wear on the brake pads,that also brings your brake light to lit on the dash.
