01 X5 3.0, Battery, Alarm, Warning lights

[Mongo]

I have been experiencing many weird problems. Something was killing my battery. After the battery finally developed a bad cell I replaced it. While dealing with the constant battery issue my alarm started to go off regularly and even a few times when I was driving. Now the Anti Rollover warning lamp is on and doesn't go away(Its a triangle with an arrow wrapping around it). Everything I read suggested that the Alternator could be the culprit. With the prior battery problems it seemed to make sense. I replaced the Alternator today and the light hasn't gone away?

I don't know if this is related or not but last week my brake light came one, the pedal is soft and ABS isn't working.

Anti rollover warning lamp?



Recheck your owners manual for the description of that warning light. The ealier e53s may not have the "4x4" written at the bottom like the pages from my 06 owners manual seen below. But ASC+T/DSC/ABS/BRAKE warning lights are related:

Since the light is on, did you push the DSC button? Perhaps you disable the DSC. If you try pushing the button and the light still remains on connect your computer to it and read the trouble code for the light. Don't have the software to read the trouble code? Get it scan and tell us what the trouble codes are.
