Scheduled maintenace is provided for the first 4 years or 50k miles, whichever comes first. That means the Oil change at 15k, Inspection I at 30k, and Oil change at 45k is provided, along with the usual wiper blades, brake pads, etc...

BMWs have approx 15k service intervals. So yes, at 30k there will be an oil change plus Inspection I service, provided at no cost.
