Freightliner Sprinter, 907

Additional Notes

• All five configurations listed — spanning the Sprinter 2500, 2500 CDI, 3500, 3500XD, and 3500XD CDI AWD variants in the 907 body generation — share an identical transfer case fluid capacity of 1 liter, indicating a compact, single-unit transfer box design consistent across the AWD lineup for 2018-2022.
• The 1-liter capacity figure represents a service fill volume, which is the amount of fluid required during a routine drain-and-refill procedure rather than a full overhaul or component replacement scenario where residual fluid retention would differ.
• The Freightliner Sprinter 2500 AWD (OM651), 907 designation identifies the OM651 as a 2.1-liter four-cylinder diesel engine, and the same 1-liter transfer case capacity applies whether the variant is listed with or without the explicit OM651 engine callout, confirming the transfer box hardware is shared across those sub-variants.
• The use condition listed as "flexible (on board maintenance system)" means the service interval is not fixed to a set mileage or time period. Instead, the vehicle's onboard computer calculates the interval dynamically based on actual operating conditions, adjusting the service reminder accordingly.
• A flexible interval tied to an onboard maintenance system contrasts with fixed severe-duty or normal-duty schedules. No separate severe or normal use interval is specified for the transfer case fluid across any of the listed configurations.
• The 3500 and 3500XD variants are grouped together in one row entry, reflecting that both share the same transfer case fluid capacity of 1 liter despite the 3500XD carrying a higher gross vehicle weight rating than the standard 3500.
• The CDI designation appearing in the Sprinter 2500 CDI AWD and 3500XD CDI AWD rows refers to Mercedes-Benz's common rail direct injection diesel technology. The transfer case fluid capacity of 1 liter remains unchanged relative to the non-CDI-labeled AWD rows, indicating the transfer box specification is independent of the engine injection labeling convention used in those type designations.
