What does the system do?
Some low-pressure EGR systems use an exhaust flap to establish the pressure difference needed for recirculation. It works with the valve, cooler and intake system.

How an EGR exhaust-pressure flap supports recirculation and why it must be distinguished from an exhaust sound valve.

Function, changes and requirements
What does the option mean?
This entry concerns that EGR-related flap. Its name alone does not establish location or the exact requested modification.
What do we check on your vehicle?
We first identify the system and scope, then assess pressure, flap position and EGR flow together. The exact control unit, software version, fitted hardware and intended use determine the scope. A configurator entry does not replace this assessment.
Frequently asked questions
Does every vehicle support this function?
No. We check the vehicle, control unit and software against the actual supported function. Include existing faults and modifications. Transmission functions also require the exact gearbox version.
Does selecting an option approve its use?
No. Changes to emissions, noise or protection functions can affect legal use and operating safety. This page promises no road approval; diagnosis and a permissible repair are considered first.
