How to Fix E13P400 Mercedes Fault Code? – Find The Answer Here
The E13P400 Mercedes Fault Code is a critical warning that can prevent your vehicle from starting, even when the AdBlue system is fully replenished. If you’re facing this issue, understanding the AdBlue system and following the right repair procedures can save time and money. This guide provides a step-by-step process to resolve the error and get your vehicle back on the road.
What is the AdBlue System in Mercedes?
The AdBlue system is a key component of diesel vehicles, designed to reduce harmful nitrogen oxide (NOx) emissions. AdBlue is a urea-based solution injected into the exhaust system, converting NOx into harmless nitrogen and water.
- Purpose: Ensures compliance with environmental regulations.
- Warning Signs: When AdBlue levels are low, your dashboard will display a warning to refill it. Ignoring this warning can lead to reduced engine performance and eventual failure to start.
Understanding the E13P400 Mercedes Fault Code
The E13P400 Mercedes Fault Code often appears when the AdBlue system encounters a restriction. Despite refilling the AdBlue tank, the system may still display a warning such as “Start not possible in XXX km (miles).” This is an AdBlue system limitation error commonly seen in vehicles like the Mercedes E212.
Symptoms of E13P400 Fault Code
- Engine Won’t Start: The car’s system prevents ignition as a safety measure.
- Limited Speed and Power: The vehicle’s speed is restricted to reduce emissions.
- Multiple Error Codes: Additional codes such as 16D300, 16D400, P13E300, and others may appear during diagnostics using tools like Xentry.
