Mercedes-Benz W176 A220 CDI (OM651) Intake Manifold | Genuine Replacement

Description

If your Mercedes-Benz A220 (W176) is showing a “Check Engine” light, experiencing a significant loss of power, or suffering from rough idling, your Intake Manifold may be the culprit. On the OM651 engine, the intake manifold is a complex assembly that houses the swirl flap motor/actuator. Over time, carbon build-up (a common side effect of EGR operation) can cause these flaps to seize or the internal linkages to break, leading to vacuum leaks and “Boost Pressure” fault codes.

Our workshop-vetted original intake manifolds are the professional solution to restore your engine’s airflow efficiency and performance.

• Integrated Swirl Flap System: These assemblies include the factory-spec swirl flap mechanism, critical for maintaining proper air-fuel mixing at low RPMs.

• Leak-Free Construction: Genuine Mercedes-Benz manifold housings are reinforced to withstand high boost pressures, preventing the “hissing” leaks common in inferior aftermarket replacements.

• Condition: Premium workshop-vetted original component; inspected for housing integrity, clean internal ports, and smooth movement of the actuator linkage.

Signs Your OM651 Intake Manifold is Failing:

• “Check Engine” Light (CEL): Frequent P-codes related to “Intake Manifold Runner Control” or “Boost Pressure Deviation.”

• Sluggish Acceleration: The engine feels “choked” or unresponsive, particularly when pulling away from a standstill.

• Excessive Smoke: If the swirl flaps are stuck in a closed position, you may notice increased black smoke from the exhaust due to an overly rich fuel mixture.

• Visible Oil Leaks: Often, the seals around the manifold runners or the actuator rod can begin to seep oil, which is a telltale sign of internal wear.

Workshop Pro-Tip: The OM651 engine is notorious for carbon build-up in the intake tract. When replacing your intake manifold, it is highly recommended to have the intake ports on the cylinder head manually cleaned of carbon deposits. Simply bolting on a new manifold without addressing the ports will leave your engine “choked” and can cause the new manifold to trigger the same fault codes shortly after installation.
