Mercedes Sprinter DEF Tank Heating Unit – Bosch OEM | #9064700453 / F01C600230 (2010–2014)

DESCRIPTION:

The DEF tank heating unit is one of the most common failure points in the NCV3 Sprinter's BlueTec emissions system — and when it goes, it takes the level sensor and temperature sensor with it. A failed heater means DEF can freeze in cold weather, the ECU loses fluid level data, and fault codes stack up fast. This Bosch OEM replacement heating unit restores full DEF system function and clears the fault pathway before derate conditions set in.

What's Included

This is a complete DEF tank heating assembly — heating element, fluid level sensor, and integrated temperature sensor — ready to install.

What This Part Does

The DEF tank heater keeps diesel exhaust fluid above its freezing point so the SCR system can operate in cold weather. The integrated level sensor monitors fluid quantity and sends tank level data to the instrument cluster and ECU. The temperature sensor ensures the heater activates at the correct threshold. When any of these components fail, the ECU triggers warning lights — and if left unaddressed, engine derate follows.

Common Fault Codes Associated with This Unit

• P203A, P203D, P209F — DEF level sensor signal fault
• P205B, P205C — DEF temperature sensor fault
• P20BD, P20BE, P20BE1B — DEF tank heater circuit performance fault
