奔驰氧传感器 A0045425318 56028765AA 234-4718，多编号匹配奔驰多款

Oxygen sensor direct replacement for Mercedes-Benz OEM A0045425318, also compatible with 56028765AA, 56028584AA and 234-4718; highly versatile with no matching concerns. Its core function is real-time monitoring of exhaust oxygen content, sending signals to the ECU to precisely control injection amount and ensure combustion efficiency. Fits Mercedes-Benz multiple models including C-Class, E-Class, M-Class, etc.; verify interface before installation. Replacing resolves high fuel consumption, weak acceleration, and frequent check engine lights; emissions compliance is restored. If idle is unstable, exhaust smoke appears, or fuel consumption spikes, the oxygen sensor is aging; replacement saves fuel and worry.
