Hello,

i'm having some trouble with the mentioned car. I did a stage 1 remapp (viezu file service). Car operates normally with a great power increase but while driving on the highway and doing pulls with 4th, 5th gear it looses all power (no turbo) and this DTC is registered (P111000 - Turbo boost actuator (actuator stuck open). After ignition cycle the car operates normally. I tested the actuator and all seems to work fine. The turbo isn't sticking and works great untill you get to the highway. There's no turbo position sensor on so i cannot see what's happening while driving. Also loaded back the original map and fault didn't come back. Any advice would be great!

Thank you!
