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, altering nozzle needle-to-seat positioning.	Clean with b-osCH special ultrasonic cleaning agent for 300 minutes; replace with 0986445005 OE nozzle (DLLA152P2410) if coating is severely worn; soak the new nozzle in 100℃ hot diesel for 28s before installation to remove anti-rust oil, avoiding reconditioned nozzles that sacrifice performance.
Injection Precision Decline	Sensor malfunction, internal valve wear, pressure stabilizer failure, nozzle angle deviation, signal interference and improper calibration, leading to altered fuel delivery.	Replace 0986445005 OE sensor and internal valve; recalibrate injection pressure to 6000–7000 bar and nozzle angle to 180°; conduct professional anti-interference adjustment to restore original precision, ensuring consistent fuel delivery.
