2003 bmw abs, brake light on. no speedometer

have you tried disconnecting the battery again?

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,

You may need to replace your brake pads and one of your sensors on the wheels.

If it has a problem, then you will get the abs light.

The best way to proceed is a get a computer read out and also look at your brake pads before proceeding with changing them.

sounds like an abs sensor has gone at the rear ,this can knock out the speedo as well

hi...sorry little confused..bmw? or ford focus? if bmw you can try checking on the passenger side where you will find the speed sensor and the brake light sensor, if both have come on then they might have become disconnected from the plugs on that side ....hope this helps

many reasons for this. A bad relay can do it, or a wheel speed sensor can to. Also the relay may be at fault. You can have the codes checked for free at any Auto Zone and they will tell you what part is bad

i need anyone one to help me with this problem, i have a BMW328ci and i tried tyo get out of my house this morning and all roads were frozen and the car started sliping and i activated the dcs button and car was still slipering and then brake, ABS, CBC & DSC lights turned on and i need to know how i can reset these lights so they can come off

Probably the Abs Module.Are the ABS, Brake,Traction Indicators on? You may call or e-mail me @ [email protected] or 318-289-4999

It's not the fuse. You need to jump start the diagnostic cable. First you need a battery of 9v and short the + and - terminal to the diagnostic cable. Then you will see smoke. After that it should work fine.
