The DEF system plays a critical role in reducing harmful emissions and ensuring your vehicle complies with environmental regulations. Our skilled technicians are experienced in diagnosing and repairing DEF system issues, getting your Sprinter back on the road quickly and efficiently.
What Is the DEF System?
The DEF system is an essential part of modern diesel vehicles, including Mercedes Sprinter vans. It uses a mixture of urea and deionized water (Diesel Exhaust Fluid) to reduce nitrogen oxide (NOx) emissions through a process called Selective Catalytic Reduction (SCR). This process converts NOx into harmless nitrogen and water, helping meet stringent emission standards.
Common DEF System Issues with Sprinter Vans
DEF Tank or Injector Problems
-
The DEF injector can clog, or the tank heater might fail, leading to issues with fluid delivery.
Sensor Failures
-
DEF quality sensors or level sensors often malfunction, causing false warnings or limiting engine performance.
Crystallization
-
DEF fluid can crystallize in the system, blocking critical components such as the injector or lines.
Poor DEF Quality
-
Contaminated or low-quality DEF fluid can damage the system and trigger warnings.
Software or Communication Errors
-
Faulty communication between the DEF module and engine control unit (ECU) can result in error codes and reduced functionality.
