Ignition Knock Sensor for Audi and Volkswagen

Global Parts 1815054 is an ignition knock sensor used to monitor engine vibration patterns associated with pre-ignition and detonation. It is a direct-fit style sensor for select Audi, Volkswagen, and Porsche applications, including Audi A3, A4, A5, A6, Q3, Q7, S3, TT Quattro, TTS Quattro, and Volkswagen GTI, Golf R, Arteon, Atlas Cross Sport, Amarok, Golf, and Passat.

  • Part number: 1815054
  • Knock sensor location: engine block, cylinder head, or intake manifold, depending on application
  • Connector type: female oval connector
  • Terminal type: pin
  • Terminal quantity: 2
  • Connector quantity: 1

How This Sensor Works

The knock sensor detects unusual engine vibrations caused by detonation or pre-ignition and sends that signal to the engine control system. On turbocharged and direct-injection vehicles such as Audi A3 Quattro, Audi S3, Volkswagen GTI, and Volkswagen Golf R, accurate knock detection helps the ECU manage ignition timing and engine operation more precisely. Global Parts 1815054 is built to match the listed connector and terminal configuration for the specified applications.

This part cross-references Standard Ignition KS448 for the same application.

Common Symptoms It May Address

  • Check engine light related to knock sensor or ignition timing faults
  • Audible pinging, spark knock, or detonation under load
  • Reduced engine performance caused by timing correction
  • Rough running or hesitation during acceleration
  • Stored fault codes tied to abnormal combustion detection

Installation Notes

Verify connector shape, terminal count, and sensor location before installation. This sensor uses a female oval connector with two terminals and a pin-style terminal design. Confirm the vehicle application carefully, especially on 2015 Audi A6 Quattro models with a black connector note, and compare the original sensor to the replacement before service. Fits 2015-2020 Audi A3 Quattro, 2017-2024 Audi A4 Quattro, 2022-2024 Audi A3, and 2022-2024 Volkswagen GTI among other listed applications.

Quality Assurance

Global Parts 1815054 is an emission control sensor replacement built to the listed OE-style fitment and connector specifications. It is referenced to OE and aftermarket part numbers for the same application, including Standard Ignition KS448 and part number 1815054 for catalog matching.
