oNCE THE BATTERY LIGHT COMES ON, IT MEANS THAT THERE IS A PROBLEM WITH UR CHARGING SYSTEM. mOST LIKELY THERE MIGHT BE A PROBLEM WITH UR ALTERNATOR. u SHOULD LIAISE WITH AN AUTO-ELECTRICIAN

was your BMW over heated?

I've had the same problem twice on my 1999 528. The problem is your ABS module. (Bosch 5.7 to be exact.) The failure mode is temperature sensitive and shows up after driving. To test this, turn off the car, get a can of freeze spray and cool down the module. Inverting a can of compressed air used for computer cleaning works too. Give it a healthy freeze, then start up the car again. If the lights are out, then you know your problem. 
All sorts of things don't work when the module is bad. Speedo, windshield washers only give you one speed, fuel gauge drifts back and forth, cruise control,  check engine lights, airbag lights .... and so on, you get the picture, basically anything connected to the computer. My new (great) mechanic calls this the BMW christmas tree. 
You can either replace the module with a new one from the dealer, very expensive, or get it rebuilt. There are a number of rebuilders out there, so take your pick. I've used ModuleMaster in the past and they've been great. $300 and works like a charm. Google them to find their web site, and good luck.

Using the indicator stalk, navigate to the tyre pressure reset option, press the reset button twice in short succession but hold it in the second time until a tick appears on the display
