Spectra Premium MA259 mass air flow sensor for the 2003-2005 Mercedes-Benz C230 4-cylinder 1.8L measures the air entering the engine and reports it to the engine computer.
A rough idle, hesitation or a check-engine light can be signs that the sensor is wearing out. These signs alone do not prove the sensor is the problem, because a leak in the intake tract is another common cause. This listing is one sensor, and the engine takes one.
It fits the 2003-2005 Mercedes-Benz C230 with the L4-1.8L engine.
