VDO Gauges A2C59506395 Ignition Knock Detonation Sensor

The VDO Gauges A2C59506395 is an OE-quality ignition knock sensor designed to monitor and detect engine detonation in real-time. This sensor monitors pre-detonation of the air-fuel mixture by detecting shockwaves that resonate through the engine block and emit audible knocking or pinging sounds. When the knock sensor detects a knock or ping, it relays that information to the engine computer so the computer can adjust engine timing and the amount of fuel entering the engine to stop the pre-detonation.

Key Features:

• Black housing with 3-pin electrical connector
• 280mm (11 inch) cable length
• Manufactured in France to OE specifications
• Made by VDO, a division of Continental Corporation with over 80 years in the automotive industry
• Deploys groundbreaking bandwidth technology for maximum precision
• Cross-references to BMW OEM part number 13627598861

Prolonged pre-detonation can damage cylinder walls, pistons, head gaskets, cylinder heads, spark plugs, and engine valves. Knock sensors are mounted directly to the exterior of the engine block to pick up vibrations created by pre-detonation. This sensor helps protect your engine while reducing fuel consumption by allowing the engine management system to optimize performance near the knock threshold.
