AdBlue error
DPF error
EGR error
DEF error




The AdBlue metering valve is a critical part of your vehicle’s emissions system, controlling the precise dosing of diesel exhaust fluid in the engine compartment and ensuring proper transmission operation. When this valve, air equipment or related sensors trigger a dash warning, many owners of Mercedes vans and NCV3 Sprinters face costly repairs or lengthy downtime. Our kit offers a simple way to clear those error codes without removing or replacing any parts, letting you keep driving and save on parts and labor.
The metering valve (also known as a metering device Mercedes uses in SCR systems) regulates fluid flow based on engine load, fuel pressure control and oil level demands. In NCV3 Sprinters, this valve often sits near the AdBlue tank and pump module. When the valve sticks or sensors misread fluid levels or air intake signals, the ECU logs a fault code, illuminating the check engine light. Rather than tearing into the engine compartment or ordering spare parts from the sale Sprinter parts inventory, you can use our tool—see our page for details—to reset the error and maintain normal operation.
This solution communicates directly with the vehicle’s control unit to disable AdBlue metering error messages. By emulating the expected signals from the metering valve and related emission equipment, our tool prevents the ECU from flagging faults. Installation takes minutes and requires no special tools—just a connection to the diagnostic port. Once in place, you can:
Our products are designed for reliability and ease of use. Unlike bulky aftermarket kits or complete DPF delete exhaust solutions, this tool focuses solely on clearing dash errors from the AdBlue metering system. You won’t need to browse the spare parts section or worry about compatibility—everything you need comes in a single package:
Rather than dismantling parts in the engine compartment or ordering expensive metering valve assemblies, our solution offers a cost-effective alternative. You benefit from:

SCR total delete – no longer necessary to repair the SCR system and refill the AdBlue fluid
We suggest deleting all of the following components together (SCR, EGR, Flaps and DPF) as all of these elements work together as one system
Temporary solution – start the engine and drive to workshop without limitations but the SCR still needs to be repaired
