A0290742202 is supplied as a remanufactured replacement nozzle. Cross-reference numbers: A0290742202. Application recorded for this part: Fits Mercedes-Benz. Spray pattern is set here. Hole geometry, needle lift and seat condition determine droplet size and penetration, and therefore how completely the charge burns. A seat that no longer seals will weep, producing carbon, poor starting and smoke even when the rest of the injector tests acceptably. Nozzle faults usually show as poor atomisation: smoke that will not clear, hard starting, rough combustion, higher consumption, and heavy carbon around the tip when it is removed for inspection. Before ordering, check whether the fault really originates here. Poor spray often starts upstream — supply pressure, contamination, or a high-pressure pump no longer delivering — and replacing only the nozzle leaves the cause in place. Cleanliness decides the outcome here. Work with the bore and seat scrupulously clean, fit new copper washers and seals, torque to specification, and check whether the engine needs injector coding after reassembly. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
