Issue with TCS and S-Mode
 

Hi all.
I am having issues with the slip light stuck on, unplugged the battery and pressed the brake to discharge and reset everything worked once for me a long time ago. No brake light or other warning on the dash and fluid level is max. It's been like that since I got it back from the TT install. I asked them about it and they said it's from the Dyno and should go away but it's been a few hundred miles

Also yesterday after some hard acceleration on the highway the car showed "warning S-Mode" and I was not able to turn it back on.

Any thoughts?
