Potential Problems & Corresponding Solutions

Potential Problems	Root Causes (Product-Related)	Targeted Solutions & Product Matching
Nozzle Carbon Deposition & Clogging	Coating wear after long-term high-load use, low-quality fuel, impurity acc-umulation, improper maintenance and dust entry during transportation, which is a common issue caused by fuel contamination and poor filtration.	Clean with b-osCH special ultrasonic cleaning agent for 200 minutes; replace with 0414755015 OE nozzle (DLLA158P2502) if coating is severely worn; soak the new nozzle in 90℃ hot diesel for 15s before installation to remove anti-rust oil and ensure tight fit, and clean the filter simultaneously. Avoid collision with hard objects during cleaning and use a proper fuel/water separator to prevent future clogging.
Injection Precision Decline	Sensor malfunction, internal valve wear, pressure stabilizer failure, nozzle angle deviation, signal interference from truck electrical systems and improper calibration, which can lead to uneven fuel supply and reduced engine performance.	Replace 0414755015 OE sensor and internal valve; recalibrate injection pressure to 5200–6200 bar and nozzle angle to 180°; conduct professional anti-interference adjustment to adapt to heavy-duty truck electrical system characteristics, and recheck each cylinder's fuel supply uniformity to restore original precision.
Fuel Leakage	Aging of high-temperature sealing ring, improper installation torque, corrosion of sealing area, damaged gaskets due to vibration during transportation and uneven installation, a critical fault that may cause engine damage and safety hazards.	Replace with 0414755015 OE high-temperature sealing ring and gaskets; re-install with 92–97N·m torque; clean and anti-corrode the sealing area with b-osCH special agent to enhance corrosion resistance under complex working conditions, and check seal tightness after installation to prevent leakage and potential safety risks.
Slow Response Speed	Internal valve blockage, sensor signal delay, insufficient fuel supply, component wear under long-term heavy load of heavy-duty trucks and dirty fuel filter, which can affect engine responsiveness and performance.	Clean internal valve with b-osCH special cleaning agent; replace 0414755015 OE sensor if signal is delayed; check fuel supply system, replace worn parts with OE-spec products and replace fuel filter to restore response speed, ensuring adaptation to frequent start-stop needs and maintaining stable engine operation.
