Q: Distronic plus, parktronic inoperative, pre-safe limited, ECS off during driving.

After getting an ECU tune from Eurocharged, and done service B3 on last Friday, I drove all the way to vegas without any issue. However, I was driving on my way back to LA from vegas using the distronic plus cruise last night, suddenly I felt a stun of the car and the screen showed distronic plus inoperative, parktronic inoperative, pre-safe limited ECS off and completely lost throttle. Had to pull over and restart the engine then everything looked fine except the engine light. Later, the car was feeling slow and the RPM won't go over 4k. It happened again about 30 minutes later. I was lucky that no car was behind me since it's almost midnight but I felt very unsafe. I am a new owner of this CPO 2012 cls63. The mileage is around 31500 miles now. I am not sure if it's caused by the ECU tune.

My car has 31500 miles.
