Product Information

Evaporative Emissions System Leak Detection Assembly

An evaporative emissions system leak detection pump (LDP) is a component of the EVAP system that pressurizes the fuel system to check for leaks. By pumping air into the system, it helps the engine control module (ECM) detect even small vapor leaks that could allow fuel vapors to escape into the atmosphere. This process ensures emissions compliance, reduces environmental impact, and maintains fuel system integrity.

Evaporative Emissions System Leak Detection Assembly Failure Symptoms
  • Check Engine Light (CEL) illumination, often with EVAP-related diagnostic trouble codes.
  • Strong fuel odors, caused by undetected vapor leaks.
  • Failed emissions test, due to the system’s inability to properly monitor for leaks.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi 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 Audi parts box and find an OEM branded part inside, simply with the addition of an Audi 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.
