Key Features

• Ignition knock (detonation) sensor for engine vibration monitoring
• 3-terminal pin design with oval female connector
• Fits gray-connector applications on many Audi and Volkswagen vehicles
• Direct-reference part number: 1815034
• Cross-references Standard Ignition KS356 and KS480 for the same application

Detailed Description

Global Parts 1815034 is used on the engine block, cylinder head, or intake manifold to detect unusual vibration caused by engine knock. By sending the signal from the sensor to the engine management system, it supports proper ignition timing control on vehicles such as Audi Q5, Audi S4, Audi S5, Audi A6 Quattro, Audi Q7, Audi R8, Audi A8 Quattro, Audi A7 Quattro, Audi A4 Quattro, Audi A4, Audi A6, Audi A5 Quattro, Audi SQ5, and Volkswagen Touareg. This part number 1815034 is listed for multiple gray-connector applications across 2005-2017 model years.

What It Helps Address

• Knocking or pinging caused by abnormal combustion
• Check engine light concerns related to knock sensor faults
• Erratic ignition timing from inaccurate detonation feedback
• Reduced engine smoothness under load or acceleration
• Fault codes tied to knock sensor circuit performance

Installation Notes and Tips

Verify connector shape, terminal count, and connector color before installation. This sensor uses a female oval connector with 3 pin terminals, so matching the OE-style plug is important for proper fitment. Confirm the exact vehicle application and engine configuration, especially on Audi R8, Audi A8 Quattro, and other models with cylinder-specific notes. Global Parts 1815034 should be installed in the original sensor location on the engine block, cylinder head, or intake manifold as equipped.

Quality Assurance

This knock sensor is built to match the listed OE-style electrical and connector specifications for the stated applications. It is cataloged for direct replacement use on confirmed Audi and Volkswagen fitments, including Audi Q5 and Audi S4 applications with gray connectors.
