All turbo cars burn oil!! This is my first BMW but not my first car with a turbo so I know its normal. It actually took longer than expected mine came on around 7000miles. process was quick and easy.
I drove straight to the service area and told the guy standing out there he goes to a cabinet they have setup outside grab a quart fill it and run engine check from idrive. no paper work or exchange of names or anything. process was under 10mins.
