Mercedes-Benz W176 A220 CDI (OM651) Fuel Injector | Genuine OEM Replacement

Description

The OM651 engine relies on high-precision Piezo-electric fuel injectors to deliver the exact amount of fuel required for clean, efficient combustion. When an injector fails—often due to internal solenoid breakdown or nozzle tip carbonization—you will notice a rough idle, engine misfires, excessive smoke, or even the dreaded “Limp Mode.”

Our workshop-vetted original injectors are the professional standard for the W176 A220 CDI. These units are tested for spray pattern, leak-back rates, and electrical resistance, ensuring they integrate perfectly with your engine’s ECU without causing long-term fuel trim imbalances.

• Precision Injection: Restores the exact fuel atomization required for the OM651’s high-pressure common-rail system.

• Engineered for Efficiency: Eliminates “injector knock” (that distinct rattling sound) and reduces black smoke caused by an over-fueling or dripping injector.

• Condition: Premium workshop-vetted original component; verified for zero leak-back, correct solenoid actuation, and clean, obstruction-free nozzles.

Signs Your OM651 Injectors are Failing:

• Rough Idling: The engine shakes noticeably when idling, which often smooths out once you start driving.

• Poor Fuel Economy: A sudden drop in kilometers per tank without any changes in your driving style.

• Engine Misfire/Limp Mode: The engine feels jerky or loses power under heavy acceleration; diagnostic scans will often show “Cylinder Misfire” or “Injector Control Circuit” codes.

• Increased Exhaust Smoke: A dark, soot-filled exhaust, especially during cold starts or hard acceleration.

Workshop Pro-Tip: When replacing an injector, always replace the copper crush washer (fire ring) and ensure the injector seat in the cylinder head is perfectly clean. If the seat isn’t perfectly flat and clean, the new injector will “blow by” (leak exhaust gases), which will cause a ticking sound and eventually melt the injector body. You must also code the new injector’s IMA (Injector Management Adjustment) number into the engine ECU using a diagnostic tool, otherwise the engine will not run smoothly.

Key Features:

• Perfect Compatibility: Designed specifically for the OM651 engine series in the W176 chassis.

• Reliability: Tested to ensure they meet factory flow-rate specifications, protecting your engine from future knock or piston damage.

• Quality Assured: Vetted for both electronic responsiveness and mechanical seal integrity.
