On the 1-2 shift it didnt up shift, got out of it and smacked her to3rd (dct bars went from 6 to3 again) then on the 2- 3shift same thing, wouldnt upshift. Got out of it and packed up for the evening. On the way home I tried a 1-2 shift at 7800 rpm. Car shifted, but engine light came on and a 7000 redline. Pulled over, stopped car and restart and it went back to normal, but a service engine soon light is now on. Andrew at AR pulling codes tomorrow to see whats up. Im staying out of throttle until we figure out the issue. I have zero desire to blow a DCT.
Very interested to know what the engine faults are. There are a lot of torque management parameters in the DME which can affect DCT operation.
