VAG Knock Sensor - Part Code 030905377D

This VAG knock sensor, identified by part code 030905377D, is a critical component for maintaining your vehicle's engine health. Its primary function is to detect abnormal vibrations or 'knocking' within the engine cylinders, which can occur when the fuel-air mixture ignites prematurely. This premature ignition, known as detonation or pinging, can lead to significant engine damage if left unaddressed. Upon detecting knock, the sensor sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing and fuel mixture parameters to eliminate the knock, thereby protecting the engine from harmful stress and potential internal damage. This real-time adjustment is crucial for both engine longevity and optimal performance. Crafted by VAG, a trusted name in automotive parts, this knock sensor is built to meet stringent quality and performance standards. Its direct fit design ensures compatibility with specified VAG models, making installation straightforward. Replacing a faulty knock sensor is essential for restoring proper engine operation, improving fuel efficiency, and preventing costly repairs down the line.
