It's telling you that there are problems in the systems. Charging, brakes. Not sure about the triangle.

turn off radio to keep from losing code.remove negative battery cable.disconnect wires from alternator .mark wires with tape to be sure they go back in the same place.loosen belt tension remove belt .if you have VR6-AAA-ENGINE remove the belt tensionsr from cylinder head .remove alternator adjustment bolt followed by pivot bolts .slowly lift alternator from bracket.smile take a deep breath dont need many tools.all you need is the basic tools. basic 3/8 socket set and open -close box end wrenches 13 up to 18 metrics.

SOURCE: The ABS,Brake Light,Battery light go on and off sporadically while driving.Does this indicate an Alternator failure or a sensor/computer problem?

yes it's most likely a alternator problem,usually the internal diode bridge breaks causing all lights you mentioned to come on,if this happens at a idle open the hood and remove green connector on alt.if lights go out you've found the problem

This is normally a low voltage from the alternator condition. Hook a voltmeter to the battery and note the reading. Should be 11.6vdc to 12.2vdc. Start the car, after a minute or so it should be around 13 to 14 vdc., if not then the alternator may be bad

Battery light is on when idleing, but when i accelerate battery light goes out


Two things can make the bat light come on at idle but go off above idle.
The belt could be slipping because it is not tight, or glazed, or the alternator could be defective.
Once the engine starts, the alternator should be making enough current to "turn the light off". The light is grounded thru the alternator until it is charging, which reverses that circuit and kills the ground source for the light.
If you are sure the belt is ok, I would have the alternator bench tested, because usually if the belt is slipping it slips more at higher speeds.

How do i get the abs/ yellow triangle of I've


I quote some details from BMW's owners...
Symptoms: Dreaded yellow triangle, ABS light, and CEL on. All other functions (speedo, tach, cruise control, trip computer, etc) working.

Procedure: Pull the ABS controller out and disconnect it from the wiring harness. Mine is under a panel to the left of the glove compartment. Remove the wiring backshell so you can get at the wiring connections on the back side of the connecting plug (you need to be able to see the colors of the wires and get a Ohm meter probe on them).

Using a Bentleys Electrical Manual find the connection diagram for the wheel sensors to the ABS Controller. The pin designators will most likely be wrong (they were for mine) BUT the color designators for each of the wires is correct.

Example: Right Rear sensor is connected by two wires, one blue and one blue green.

Connect Ohm meter across these two pins. NOTE: I wound paper clips around the probes to make a very small probe tip which helps. Write down the resistance reading. Mine was 3.08k ohms.

Work through the other 3 wheels and write down the resistance readings. If any of the pairs is open (i.e. infinite resistance) you have a bad connection between the ABS Controller and the wheel sensor. You can then remove the affected wheel, unplug the sensor, short out the pins on the plug (not the wheel sensor part but the chassis wiring part) and if the ohm meter is still reading open you have a broken cable between the wheel sensor and the ABS controller. If the cable is good connect the ohm meter across the wheel sensor itself and if the cable still reads open you have a bad wheel sensor, replace and retest.

Here is what I found. All wheels read 3.08k ohms except the right rear which read 4.4M ohms. This sensor was replaced during my rebuild exercise and it looks like they provided the wrong part. I replaced the part with a dealer item and retested. 3.08k ohms was read with the new part. Reconnected everything and the ABS light went out, the yellow triangle light went out. I used my OBDII computer interface to clear the CEL light and all is well again.

Total testing/repair time: 2hrs and 35 minutes!

Here is my theory. The "older" ABS Controllers (like mine) use sensors with the lower reisitance (3.08k ohm) while the newer Controllers use the higher resistance sensors (4.4M ohm). The part I bought was from a 02 E39! I can return it but I think I will use it to test my 00 528 problems first.

Additionally, I suggest check charging system (alternator/power module/battery) has a defect that a professional BMW technician should look at, Most probably the alternator is toast.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

My abs light and my battery light is on. new battery ran down in less than an hour.


check for voltage from the alternator, charge the battery ,, with a multi meter set to DC volts ,, check voltage, you should have a reading just a little over 12v dc, then start the car,, check again, you should get a reading between 13.5 volts to 14.5 volts , if you have that your alt is good,, if not Its not charging the battery as your driving, having a low battery makes the computer go crazy and it looks for anything wrong,, Ive had dash lights for everything light up ,

My Car shut off, I found out it was the


ABS is Advanced Brake Systems, but that light should flash once when the car is turned on to signal it works.
If you turn the key in the ignition forward, like you are going to turn it on, but not far enough to turn the engine over, that light should be on at a constant. with it turning itself off upon starting.
If you have a no start issue, it would have the same effect. But if it is a no start, it's not going to be a dead battery, the battery puts out enough charge to turn the engine over (on), and the alternator runs everything.
Alternators run off the belt(s) on the engine and need exact tension, in order to produce the proper amount of power.
