This is a dosage valve, a crucial component in the fuel injection system responsible for regulating the precise amount of fuel delivered to the engine. Manufactured to meet strict Volvo performance standards, it ensures accurate fuel metering for optimal combustion and emissions control, unlike a worn valve that may deliver inconsistent amounts. Operators may experience engine misfires, rough idling, reduced power, or increased exhaust smoke when this valve is malfunctioning.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Hesitation or stumbling during acceleration can be an initial sign of a faulty dosage valve. If ignored, the engine may begin to idle roughly or stall intermittently, and fuel economy will noticeably decrease. Continued operation with an incorrect fuel dosage can lead to engine damage and increased emissions.
Ensure the fuel system is properly bled of air after installation to prevent starting issues. Avoid cross-threading the fuel line connections, as this can cause leaks.
Inspect the fuel filter and fuel lines for any signs of blockage or damage.
