Just picked up my S2000 (other was nicked) and it has VSA. COming back from work yesterday, the VSA trangle and large VSA lights came up. along with the ECU warning light.

Any clues?, is it ok to drive over to the dealership tomorrow. It is under warrenty till the sumer

 

Hrmm, had a similar experience with my 135i and it was a wheel speed sensor failure. Not sure if that would hold true for the S2k. Let us know what they say.
