What It Is Used For

• Replacing a failed knock sensor that can trigger drivability concerns.
• Restoring accurate detonation detection for engine management.
• Addressing fault codes related to knock sensor circuit performance.
• Correcting rough running caused by inaccurate ignition timing input.

Installation Notes and Tips

Verify connector style, terminal count, and harness length against the original part before installation. Confirm the vehicle application by year, make, and model, since this sensor is listed across multiple BMW platforms. Use the fitment data to match the correct BMW 540i, X5, 745i, or other listed application before ordering. Part number ID0098 should be matched exactly to the catalog listing.
