FAQs

What vehicles is this knock sensor compatible with?

This sensor is designed for various Volkswagen, Audi, and Skoda models, including but not limited to VW Fox, VW Passat, Audi TT, and Skoda Yeti. Always verify compatibility with your specific vehicle's OEM part number.

Does the sensor come with a cable?

No, this CI Ignition XKS37 knock sensor is sold without a cable. You may need to reuse your vehicle's existing cable or purchase a compatible one separately.

What is the function of a knock sensor?

A knock sensor detects engine knocking (detonation or pre-ignition) and sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to prevent engine damage and maintain performance.

How do I know if my knock sensor needs replacement?

Symptoms can include a Check Engine Light, engine pinging or rattling noises, reduced engine power, poor fuel economy, and rough idling. A diagnostic scan can often confirm a faulty knock sensor.

What is the connector type?

The sensor features a 2-pin connector with a D-shaped housing.

Can I install this myself?

While possible for experienced DIYers, it is generally recommended to have a qualified mechanic install the knock sensor to ensure correct fitment, torque, and connection, preventing potential engine damage.

What are the OEM and cross-reference part numbers?

This sensor is compatible with OEM references such as VAG 030905377C and Ford 1205185. Cross-references include Bosch 0 261 231 146, Hella 6PG 013 114-301, and Siemens S107646001Z.

Troubleshooting

Check Engine Light remains on after installation.

Ensure the sensor is correctly seated and the connector is securely attached. Verify that the correct part number was installed and is compatible with your vehicle. Consult a diagnostic scanner for specific trouble codes.

Engine performance issues persist.

Confirm proper installation torque. Check for any vacuum leaks or other engine-related issues that might mimic knock sensor symptoms. Ensure the ECU has been reset or has relearned parameters.

Connector does not fit.

The sensor may not be compatible with your specific vehicle. Double-check compatibility against the OEM and cross-reference numbers provided. The connector type is a specific 2-pin D-shape.

Cross-reference your vehicle's current knock sensor part number with the listed OEM references (VAG 030905377C, Ford 1205185) and other cross-references (Bosch 0 261 231 146, Hella 6PG 013 114-301, Siemens S107646001Z).

Installation: Installation typically requires accessing the engine block where the sensor is mounted. It is recommended that this part be installed by a qualified mechanic. Ensure the mounting surface is clean before installing the new sensor. Torque specifications for the sensor mounting bolt should be followed according to the vehicle's service manual.

Care: This is a solid-state electronic component and requires no routine maintenance. Avoid exposure to excessive moisture or harsh chemicals. Ensure the electrical connector remains clean and free of debris.
