Need help with with the ABS,BRAKE,DSC Lights
 

I have a problem with my 2003 x5 4.4i with the ABS SYSTEM the abs,brake,and dsc lights came on a week ago. I notice that when i turn the truck off they go away but i turn it back on and everything its normal i drive it for 3-4 mins and and i hit the brake and the pedal feels realy stiff and when that happends the 3 lights turn on and when their on everything goes back to normal the brake pedal its normal and it brakes normal but the lights are on. Some people tell me is the abs speed sensors others tell me is the abs module please help

Only real way to determine why the lights are on is to get it scan. Regular OBD II scanners will not provide the info. You need a scanner that can read all the modules in the BMW.

Is there a scanner that will scan all the BMW modules, codes and what not, That's reasonably priced.
What's everyone using ?

I use a piece of software with an old window xp laptop. It's called BMW scanner 1.4. You can get it on Amazon.

INPA, which is factory BMW diagnostics, is also available on Ebay IIRC as a package together with the needed OBD2 cable.

The software is available on-line for free also. I got mine this way. You will need to get a cable for it, I got mine on Amazon.

Thanks Upallnight and g300d.

You're welcome, good luck solving that!

Hi UPALLNIGHT,

PA Soft 1.4 good enought to scan?
getting the lights as well (TRIFECTA)
speedometer/cruise control working..
when scan it says Front right wheel open circuit
what do i have to do?

Thanks in Advance

The wheel speed sensor needs to be replace. Buy an OE wheel speed sensor, and perhaps the connector from the main harness that attaches to the wheel sensor connector. On the three wheel speed sensors that I had to replace on my X, the harness just crumble apart when I went to detach it.

Trifecta
 

Hi UPALLNIGHT,


thanks for quick response, by the way, we replace the old abs socket since it was broken into pieces and look into posible crack or open wire, replace the wheel speed sensor that i order from amazon...

i will try check the wires again and buy OE speed sensor thais time...

thanks again :thumbup:
