Audi VW Accelerator Pedal Sensor - Genuine Audi VW 8W1723523

Product Information

An accelerator pedal sensor (also called an APP sensor) is an electronic device that monitors the position of the accelerator pedal and sends this data to the engine control module (ECM). Instead of using a mechanical throttle cable, modern vehicles rely on this sensor to regulate throttle response, fuel injection, and engine power. A properly functioning sensor ensures smooth acceleration, precise throttle control, and optimal fuel efficiency.

• Delayed or unresponsive acceleration, due to incorrect pedal position signals.
• Check Engine Light illumination, often with throttle-related diagnostic trouble codes.
• Engine hesitation, stalling, or reduced power (limp mode), caused by faulty sensor readings.

About Genuine VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
