VDO Gauges 13-62-7-598-861 Knock Sensor for BMW

The VDO 13-62-7-598-861 is a genuine OEM-quality knock sensor engineered to detect engine pre-detonation in BMW vehicles. This sensor monitors the air-fuel mixture combustion process and identifies abnormal shockwaves that create the characteristic knocking or pinging sound in the engine block.

Key Features:

• Manufactured by VDO (Siemens/VDO Continental) to exact OEM specifications
• Ground-isolated design with two-wire shielded harness to protect against electromagnetic interference (EMI)
• Direct fit replacement for BMW part number 13-62-7-598-861
• Can be installed in left or right position
• Cross-references: A2C59506395, V20-72-0113-1, ID0057

When the knock sensor detects pre-detonation, it relays real-time information to the engine control unit, allowing the computer to adjust ignition timing and fuel delivery to prevent engine damage. A faulty knock sensor can result in check engine light illumination, reduced performance, and potential damage to cylinder walls, pistons, gaskets, and valves.
