Greetings: I have a 2001 525i, just turned 100K. For the past few months the dash warning lights (ABS BRAKE Traction Control indicators)have been going on intermittently, but lately more often than not. Just the other night, the two rear brake light indicators lit up and stayed on until I turned off the ignition. Next day, back to normal. It should be noted that all systems are functioning properly, whether the lights are on or not. Is this something due to mileage wear and tear? Is this "normal? What is involved in getting these lights to function like they should? The car is in tip top shape otherwise, and has always run like a fine Swiss watch. It has been maintained by either a dealer or other certified BMW tech, and always according to schedule. Anyway, I'd appreciate any advice you may offer so I know what I may be looking at when I bring it in next week. THANKS!
