This Urea Injector is a vital component of the Selective Catalytic Reduction (SCR) system, precisely delivering Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce NOx emissions. Manufactured to meet strict Volvo standards, it ensures accurate injection rates and durability, unlike a clogged or faulty injector. Operators may observe illuminated check engine lights, reduced engine power, or increased exhaust smoke if this injector fails.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a faulty urea injector is often a warning light on the dashboard or a reduction in engine performance. If ignored, the SCR system's efficiency will decrease, potentially leading to increased emissions and further engine derating. Continued operation without addressing the issue can result in non-compliance with emissions regulations and potential engine shutdown.
Ensure the DEF lines are clean and free of crystallization before connecting the new injector. Avoid cross-threading the injector into the exhaust manifold or adapter.
It is recommended to inspect the DEF tank, lines, and pump for any signs of contamination or blockage when replacing the urea injector.
