[AML225]

About a week ago I purchased a CPO 2015 M235i with 48,000 miles on it. After a couple days of owning it, the car was telling me to put in 1 qt of oil. I stopped by a BMW dealer (different from where I purchased the car) to pick up the oil, and they offered to verify I was getting the right oil and to put it in the car for me. While doing that the tech noticed that I was almost at the end of the original 50,000 mile warranty and suggested I make an appointment to bring the car in for a "check-up" before the warranty expires. What can I expect from this? He said it would take 1-2 hours. Is this really worthwhile on a CPO car I purchased ~1 week ago?

Thank you very much for the guidance.
