Key Features

• Part number: V10-72-1177
• Ignition knock (detonation) sensor for emission control systems
• 3-pin plug connection
• Approximate 500 mm harness length
• Compact sensor body dimensions: 15 mm height, 25 mm width
• Lightweight design at 0.098 kg
• Fits a broad range of Audi A3, A4, A5, A6, Q5, TT, R8, S4, S5, SQ5, and Volkswagen GTI, Jetta, Passat, Tiguan, and CC applications

Detailed Description

The Vemo V10-72-1177 is an aftermarket ignition knock sensor used to monitor engine detonation and send timing-related feedback to the engine management system. Correct knock sensor operation is important for maintaining proper ignition timing, reducing abnormal combustion, and supporting smooth engine performance in Audi and Volkswagen vehicles.

This sensor is listed for many fitments across the 2005-2017 model years, including Audi A4 Quattro, A6 Quattro, Q5, TT Quattro, A5 Quattro, and Volkswagen GTI, Jetta, Passat, Eos, Tiguan, and Touareg. Fitment notes vary by engine cylinder group and connector configuration, so matching the original part number and connector style is essential. This part cross-references Standard Ignition KS312 for the same application.

What It Helps Address

• Knock sensor fault codes
• Erratic ignition timing caused by failed detonation feedback
• Reduced engine performance from inaccurate knock detection
• Check engine light concerns related to the knock sensor circuit
• Driveability issues tied to engine pinging or detonation control

Installation Notes and Tips

Verify the connector style, harness length, and cylinder-bank application before installation. This part is listed with multiple vehicle-specific notes, including 3-pin plug configurations and 500 mm dimensions, so compare the original sensor and OE reference numbers before ordering. Confirm the exact engine location on Audi R8, S4, S5, Q7, and related models where cylinder-group notes differ.

For best results, inspect the wiring harness and connector terminals for corrosion or damage before replacing the sensor. Use the vehicle service information for torque and routing specifications.

Quality Assurance

VEMO supplies application-focused sensor components for European vehicles, and this part is cataloged with OE-style fitment references for Audi and Volkswagen platforms. The V10-72-1177 is identified with multiple interchange numbers, including 5S11722 and 06E 905 376 A, to support accurate parts matching.
