2004 X5 4.4i 4x4 issues....seeking some help in the right direction....
So doing some research Im seeing it could be the alternator itself. One of the times the light came on I did notice that the radio did turn off? Not sure if that was a fluke or not? Other things it could be is the worm gear, speed sensors, steering sensor, uneven tire pressure, etc.... So my question is where should I start? I would love to pull the code but since my scanner doesn't have that function what would you recommend so I can possibly purchase one? Or if its even worth purchasing one? I just need a direction and what it could be now that the tire pressure light is on. I did put air into the tires yesterday at 34psi all around. So maybe thats why its on? But I believe if I get the ABS, 4x4 and forgot the other one its guaranteed its the worm gear but so far its just been the 4x4 and tire pressure. Any direction, info would be greatly appriciated!

Do you have a full scanner Foxwell, inpa, etc?
If yes then what codes do you have? Check voltage is always a good call with BMW's. Low pressure light.... Start with ride height sensors Sent from my SM-A730F using Tapatalk

I'd start with the simple stuff first... check the battery, alternator charge level.... these cars seriously have a brain fart when the electrics aren't being fed...

The tire pressure monitor uses and wheel speed senses to calculate the tire pressure variance. You need to get a scanner that can read the abs codes. You can also check the wheel speed sensors using a dvm or scope.

The Foxwell's run $150 USD or less (£99 from Amazon UK) and considering that some U.S. mechanics charge $100 or more for scanning and resetting it pays for itself the 1st time you use it. Battery voltage is truly the biggest pain in the ass with BMW's so make sure it gets load tested not just a voltage check. Sent from my SM-A730F using Tapatalk

I think that's the most cost effective route and gives you the best diagnostics. |

Yea going to check that later today with my scanner. I might go over to a Autozone and see if they can check it with there system to double check.

that just started ever since i added more air to the tires. Ill be double check that later today. My scanner has ABS capability so would it read those speed sensors?

I was even debating on the INPA so might look into those a little further as well
