So I am officially out, sorry guys!
Both throttle actuators nees to be replaced, it has to be ordered from Germany and it will take 2-3 weeks (based on BMW Gallery) to get the part
I have to retun the X1 as well and they are getting me a rental car instead. It seems like BMW loaners are paid by warranty only for 24 hours. After that, it has to be a rental car.
