I have recently gotten something like this.
I DSC lights came on . I went back to the dealer to see what was going on. And they told me it was my DSC ECU that had a malfuction. I notice there was a drop in power out on my car. I thought it was my exhaust people NOT have the right set up which made my car felt slow. But now Slower. Do anyone if this is also a problem. But i must say prior to my dash board lighting up like X-mas lights I did spend 1 full day at the race track with the MDM on so I don't know if this has cause the problems as well.
