VWS-11-062019-04-08. Service bulletin. EQUIPMENT. Warranty Information (Regularly Scheduled Maintenance Interval Time or Mileage Guidelines): The Volkswagen Customer Experience Team has monitored the claims processed through the Carefree Maintenance (CFM) program from its inception. Their findings reveal that, in many cases, the first maintenance interval service (10K) has been claimed multiple times while subsequent maintenance interval services (20K and 30K), although being performed for the customer, have been submitted erroneously. It is crucial that Volkswagen of America receives accurate claim coding information regarding the Carefree Maintenance (CFM) Program. Accurate claim data enables Volkswagen to assist Dealers to improve their CFM penetration and customer return rates. In addition, it allows VWoA to assess the perceived benefits of the program to our customers. To assist Dealer Service Departments in determining the most appropriate service number and maintenance interval to use, Volkswagen has established the guidelines in this document.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
