Delphi AS10330 Ignition Knock (Detonation) Sensor

Delphi Knock Sensor for BMW Turbo Engines

The Delphi AS10330 ignition knock sensor is built for BMW applications that require accurate detonation detection and stable engine management feedback. It is a direct-fit sensor with an oval female connector, 4 terminals, and screw mounting for the listed BMW models.

• Ignition knock (detonation) sensor for engine timing feedback
• Delphi OE-developed sensor design with calibrated output
• Oval connector shape with 1 connector, 4 terminals
• Female connector and female blade terminals
• Screw-mounted design with 540 length specification
• Direct replacement for select BMW 135i, 335i, 535i, X5, X6, M3, M4, M2, and more

OE-Style Sensor Performance

Delphi AS10330 is engineered for vehicles that rely on precise knock detection to help the engine control module adjust ignition timing. Delphi validates its sensors to OE standards and calibrates them for accurate readings, which supports consistent signal quality and helps reduce repeat repairs. This part cross-references Standard Ignition KS357 for the same application.

Common Symptoms This Sensor Can Address

• Knock sensor fault codes related to detonation detection
• Rough running caused by incorrect ignition timing feedback
• Reduced engine performance from inaccurate sensor readings
• Check engine light concerns tied to knock sensor circuit issues
• Driveability problems on BMW turbocharged engines

Installation Notes

Verify connector shape, terminal count, and mounting style before installation. The sensor uses a screw mount and a female oval connector, so the harness and mounting point must match the listed application. Follow factory service procedures for torque, routing, and connector engagement to maintain proper signal integrity.

Quality Assurance

Delphi develops and validates its sensors to OE standards and calibrates them for accurate readings. That OE-focused testing helps support dependable engine management performance on BMW 335i, 535i, X5, X6, M3, M4, and related applications.
