BMW: 3 Beeps, 3 beeps, mileage points

Question
89 325i: Randomly beeps(3x) while driving. Is it something with the locking security system?  

Answer
Peter,
 It's probably the computer (to the right of the radio) beeping.  You can set mileage points on the computer and and it will beep when you hit those points.  So say every 10 miles it will beep.  I think you can hit "Set/Resume" and it should clear it up.

 Hope this helps,
 Josh
