Mercedes-Benz recommends Servicing your Sprinter at 20K miles OR 1-year intervals. The first one at 20 is an A, then the next service at 40K is a B and so they continue to flip-flop like that every 20K.
We follow the Service Sheets to the letter especially if your Sprinter is under warranty. We want to help maintain warranty compliance and will not do anything to jeopardize your warranty.
