Spectra EM2406URH DEF Heater Overview

The Spectra EM2406URH diesel exhaust fluid heater is built for diesel emissions systems that need accurate DEF temperature control and fluid level sensing. It is a direct-fit emission control component for select Mercedes-Benz Sprinter applications, including Sprinter 2500 and Sprinter 3500 models.

By helping keep DEF from freezing during normal operation and providing a reliable level signal, this heater supports proper emissions-system function and helps reduce the risk of warning lights and speed limitation events tied to low DEF.

Key Features

• Precisely calibrated heater and temperature sensor
• Helps prevent DEF freeze-up during normal vehicle operation
• Provides accurate DEF fluid level indication
• Validated by in-house Canadian engineering review to OE requirements
• Direct replacement for select Mercedes-Benz Sprinter diesel emissions systems

Detailed Description

The Spectra EM2406URH is a diesel exhaust fluid heater for emission control systems that rely on stable DEF temperature and level monitoring. It is engineered for 2010-2018 Mercedes-Benz Sprinter 2500 and 2010-2018 Mercedes-Benz Sprinter 3500, plus 2018 Mercedes-Benz Sprinter 3500XD applications with the listed configuration notes. This part number, EM2406URH, is intended for vehicles without an AdBlue tank in the engine compartment and without code KP2 where specified.

This part cross-references Bosch F01C600232 for the same application.

What It Helps Address

• DEF freezing in cold-weather operation
• Incorrect DEF level readings
• Check engine light caused by depleted DEF
• Reduced vehicle operating speed related to DEF system faults
• Emission-system performance issues tied to heater or sensor failure

Installation Notes and Tips

• Verify vehicle configuration before ordering, especially AdBlue tank location and code KP2 requirements.
• Confirm the replacement matches the original connector, mounting, and emissions-system layout.
• Inspect the DEF tank and related wiring for contamination, corrosion, or damage before installation.
• After installation, clear diagnostic trouble codes and confirm the DEF level and temperature readings are normal.
