FAQ

Q1: How do I verify that the DLLA155S658 nozzle fits my injector?
A: You must remove the existing nozzle from your injector and check the number stamped on its side. It should match DLLA155S658 or 0 433 271 898. This nozzle is designed for specific Bosch injector bodies. Do not rely solely on the vehicle model for selection.

Q2: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. The nozzle seat must be perfectly clean. Use a new copper washer and tighten the nozzle retaining nut to the manufacturer’s specified torque (usually around 60-80 Nm, but check your engine manual). Over-tightening can damage the nozzle body.

Q3: How can I maximize the lifespan of this injector nozzle?
A: Use high-quality, clean diesel fuel and replace your fuel filters regularly. Contaminated fuel is the primary cause of nozzle failure. For long-term storage, keep the nozzles in their original packaging in a dry, clean environment to prevent corrosion.
