奔驰A180 1.6T点火线圈高压包A2749061400 A2749060600 原厂性能

When your Mercedes-Benz A180 1.6T exhibits hesitation on acceleration, unstable idle, or the engine fault light is on, or cold-start is difficult, this usually indicates ignition coil aging or insulation degradation leading to insufficient spark energy or intermittent misfire. This coil converts low voltage to high voltage to ensure spark plug ignition at the correct timing, maintaining smooth engine operation and power output. OEM numbers A2749061400 and A2749060600; compatible with Mercedes A180 1.6T (4-cylinder). During installation, disconnect the battery negative terminal and ensure the coil contact surface with the spark plug is clean; torque must follow factory standards to avoid over-tightening and damage.
