FYI QS is enabled standard with provides upshifting only. QS + you have to pay for and this enables the menu and the ability to use downshift and switch off. It has to be calibrated by the tech when downloading is done and enabled, my tech spent an hour getting it calibrated properly because he wasnt happy with it and now its buttery smooth up and down. It wasnt to start with and he said, "you wouldnt be happy with it as it was". Its very slick when working correctly. Cant help with the seat.
