Mercedes-Benz fault codes and how to clear them
Every control unit in a truck stores the faults it detects. Some codes stay in memory after the cause is gone, for example after a sensor or cable is replaced or AdBlue® is topped up, and keep a warning light on or the engine power reduced. An error code eraser clears these inactive codes from the diagnostic connector in seconds, without a diagnostic computer.
An eraser does not repair a fault. If the cause is still there, the code returns within minutes of driving. Diagnose and repair first, clear second.
The eraser does not display code numbers. To read the exact code and its meaning, use a diagnostic computer or ask your workshop.
Choose the eraser for your Mercedes-Benz
Erasers are not universal. The model series, generation and emission standard decide which one fits, so pick by the model and years in the product name.
