VDO Gauges 13-62-7-566-786 Knock Sensor for BMW Engines

The VDO Gauges 13-62-7-566-786 is an OEM-quality knock sensor designed to protect your engine from damaging detonation. Manufactured by Continental-VDO, this sensor monitors engine vibrations and helps the engine control unit optimize ignition timing for maximum performance and fuel efficiency.

How It Works:

This knock sensor utilizes piezoelectric crystal technology to detect abnormal engine vibrations caused by pre-ignition or detonation. When knock occurs, the sensor converts these mechanical vibrations into electrical signals that are sent to the engine control module (ECM). The ECM then adjusts ignition timing in real-time to eliminate the knock and prevent engine damage.

Key Features:

• OEM-quality construction manufactured by Continental-VDO
• Piezoelectric sensor technology for accurate knock detection
• Helps prevent costly engine damage from detonation
• Optimizes ignition timing for improved fuel economy
• Reduces emissions by maintaining efficient combustion
• Direct replacement for BMW OEM part number 13627566786

Important Installation Note:

Proper installation is critical for optimal sensor performance. Follow manufacturer torque specifications when mounting the sensor to the engine block. Do not use spring washers or additional washers during installation as these can interfere with vibration detection.

A failing knock sensor can trigger the check engine light, cause reduced engine performance, poor fuel economy, and increased engine knock that may lead to serious internal engine damage if left unaddressed. Replace your worn knock sensor with this quality VDO unit to restore proper engine management function.
