I have had this happen to me a few times recently while driving my 2006 R53. Under very spirited acceleration, getting near redline, the DSC light will turn on. Once it turns on it stays on until I shut off the car and it doesn't come back on after restart. I've even reset the ECU and it still happens. Current mods are a 15% pulley, Craven CAI, and a WMW Quicktune, I'm currently at 91k miles. I'm curious as to what is causing this and if it is something I need to worry about. I did a search to see what info I could find and it came up with a thread on the other site, but there wasn't a whole lot of info. Anybody have any ideas?
