What does the system do?
A flap may change exhaust routing depending on operating conditions. A rear-silencer sound valve has a different task from an engine-side EGR flap.

Function, changes and requirements
What does the option mean?
The researched supplier option changes supported flap operation, potentially keeping it open. This does not establish universal control of every exhaust valve.
What do we check on your vehicle?
We identify its location, actuator, original purpose and exhaust hardware, then assess noise and emissions implications. 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.
