I'm registered for my first HPDE school this summer (excited!) I have a 2002 530i (146k) and the DSC light won't go off. I rarely drive with DSC on, as I don't like the feel of the car with the "nanny" options on. I suspect I may need an ABS unit, but it'll be tough to shell out more $$$ after having paid for the school and related expenses (and FSU, starter, bushings, and sway bar for the car this past summer) I guess I have two questions: -Everything else on the car is drive-ready (school's checklist is all signed-off on); is it possible the instructor(s) won't care the DSC light is on? I certainly don't want to put myself or anyone else at risk, but the car has been driving great with the light on for months. -If I should just bite the bullet and get out the American Express for another garage bill, are there a few things I can do myself to check if there's just a disorder with the indicator light before I take it to my mechanic? (i.e., pull a fuse or two?) I know a lot about my car, but I'm def. not a DIYer on this complicated beast.
