What does the A1 service in 15 days mean

Hello, it's so important to learn about your vehicle maintenance in your owners guide. And by consulting a local, trusted Mercedes-Benz certified technician, independent or dealership.

If the last service was performed around 56,114 miles, the next would be logically due at about 66,000 miles.
