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.	Clean with b-osCH special ultrasonic cleaning agent for 300 minutes (following b-osch's standard cleaning parameters); replace with 0414755118 OE nozzle (DLLA158P2509) if coating is severely worn; soak the new nozzle in 100℃ hot diesel for 28s before installation to remove anti-rust oil, and clean the filter simultaneously. For safety, avoid collision with hard objects during cleaning, similar to b-osch's basic maintenance principles.
Injection Precision Decline	Sensor malfunction, internal valve wear, pressure stabilizer failure, nozzle angle deviation, signal interference and improper calibration, which can lead to uneven fuel supply.	Replace 0414755118 OE sensor and internal valve; recalibrate injection pressure to 6200–7200 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, referring to b-osch's product maintenance guidelines.
