There is no 36k service. Instead, BMW uses Condition Based Servicing which is explained in your Service/Warranty manual. Also, see "Service requirements" in your Owner's manual to learn how to read the service info from your iDrive and/or dash computer. It will indicate when the next service is due for Oil, Brakes, Brake fluid and any inspections. These are all covered ny BMW during the 4 year/50k mile warranty period.
