VDO Knock Sensor for BMW Engines

The VDO knock sensor line for BMW engines gives you an OEM-quality replacement for the ignition knock (detonation) sensor, also called a ping sensor. VDO, a Continental brand, has long supplied these sensors to BMW as original equipment. The sensor bolts to the engine block and listens for the sound of pre-detonation. It sends that signal to the engine control unit (ECU).

Key Features:

• OEM-level quality: Built by a leading original equipment supplier to BMW to meet original design and performance requirements.
• Engine protection: Helps the ECU detect knock early so it can adjust ignition timing and protect pistons, cylinder walls, valves and spark plugs from damage.
• Performance and efficiency: Lets the engine run optimal timing without knock.
• Reliable signal: Designed to maintain OE frequency response and mounting, so the signal stays accurate.
• Direct-fit replacement: Made to replace the original sensor with no modification.

A failing knock sensor can trigger the check engine light and a fault code. It can also push the engine into a reduced-performance safe mode. Replacing it with a VDO sensor restores proper knock detection and engine management. Select the specific part number in this line for your application.
