Mercedes Sprinter DEF Tank Assembly with Integrated Pump – Genuine OEM | NCV3 | #9064701700 (2016–2018)

DESCRIPTION:

When the DEF tank assembly on a BlueTec Sprinter fails — whether from a cracked housing, contaminated fluid, failed internal pump, or a heater unit that's beyond repair — the entire assembly often needs to go. This is the Genuine Mercedes-Benz DEF tank assembly for the 2016–2018 NCV3 Sprinter, complete with integrated delivery pump, ready to restore full DEF system function and eliminate the cascade of SCR fault codes and engine derate warnings that follow a failed tank.

What's Included

This is a complete DEF tank assembly with integrated delivery pump — not a tank-only unit. The pump is built into the assembly and delivers pressurized DEF fluid to the dosing injector nozzle in the exhaust stream.

What This Part Does

The DEF tank stores diesel exhaust fluid (AdBlue/urea solution) and houses the delivery pump that pressurizes and supplies fluid to the SCR dosing system. The integrated heater element keeps DEF above its freezing point in cold weather. The SCR system uses DEF to convert harmful NOx emissions into harmless nitrogen and water — without a functional tank assembly, the entire emissions control system is inoperative, leading to fault codes, warning lights, and eventually engine derate.

Common Reasons for Full Tank Replacement

• Cracked or leaking tank housing from age or impact damage
• Internal pump failure that cannot be serviced separately
• DEF contamination requiring complete system flush and tank replacement
• Heater element failure beyond the standalone heater unit repair
• Complete SCR system rebuild on high-mileage or flood-damaged vans

Important: VIN Specific

DEF tank assemblies vary by model year and equipment configuration. This assembly fits 2016–2018 NCV3 Sprinters — it is not compatible with earlier 2010–2015 NCV3 models, which use different tank assemblies. Always verify your VIN before ordering.
