P20E8 – REDUCTANT PRESSURE TOO LOW – FAULT CODE MERCEDES

The P20E8 trouble code, also known as “Reductant Pressure Too Low,” is a common issue in Mercedes vehicles equipped with AdBlue systems. This code appears when the engine control module detects insufficient pressure in the reductant delivery system. When the fault is triggered, the check engine light will come on, and a warning message may display on the dashboard. Our advanced solution allows you to clear the P20E8 code without replacing components, saving time and money while keeping your vehicle on the road.

What Does Code P20E8 Mean?

The P20E8 code indicates that the reductant pressure is too low for proper operation. This can affect the dosing system, which injects AdBlue into the exhaust stream to reduce harmful emissions. The engine control module monitors the reductant pressure sensor to ensure it stays within the required range. If the pressure drops below acceptable levels, the fault is stored in the system.

Common Causes of the P20E8 Code

The P20E8 reductant pressure sensor code can be triggered by several factors, including:

• A failing AdBlue pump unable to maintain proper pressure.
• Clogs or leaks in the reductant dosing nozzle or system lines.
• Faulty sensors, including the reductant pressure or temperature sensor.
• Issues with the control module or reductant level sensor.

These causes can result in the system being unable to dose the correct amount of AdBlue, leading to increased emissions and potential damage to the SCR system.

Symptoms of the P20E8 Code

If the P20E8 code is active, you may notice the following symptoms:

• The check engine light illuminated on the dashboard.
• Warnings about reductant levels or pressure displayed on the panel.
• Reduced engine power or limp mode activation.
• Higher emissions and possible AdBlue dosing issues.
