If I am allowed to add a piece of advice, for the health of your new car:
1. Check the service records for engine oil and break fluid. If they are almost due, overdue or there's no record, replace them at once.
2. Replace the air filter if it's older than 15.000 Km, or there's no record for it.
3. Replace
immediately the gearbox oil, regardless of your car's mileage - although it is called "lifetime oil". Buy the correct type from the dealer. You will also need two plugs p/n 23117531356. When I replaced the oil in mine, I couldn't believe how black the factory-filled one came out.
4. If your Z4M's mileage exceeds 50.000 Km, then also replace the differential oil. This one is also considered "lifetime". As above, buy the diff oil from the dealer. Aslo, two plugs p/n 33117525064 are needed.
5. For a mileage in excess of 50.000 Km, it is a good practice to replace the power steering oil. It's ATF. Since it is messy to remove it in full, it is acceptable to partially renew it. You can use a large syringe to extract as much ATF as possible from the power steering reservoir. You will be able to take out about 0.3 liter. Refill with brand new ATF, then run the car for a day, and the next day repeat the operation.
6. If the car is 3+ years old, then you may consider replacing the coolant, too.
Then enjoy your Z4 M
