What does the system do?
Oxygen sensors measure residual oxygen in exhaust. Depending on their position, they support mixture control or catalyst monitoring.

Lambda – Oxygen sensing and diagnostics
Why regulating and diagnostic oxygen sensors have different roles and what a Lambda-related request must specify.

Function, changes and requirements
What does the option mean?
The option concerns defined supported sensor or diagnostic functions. It must not be interpreted as blanket removal of all mixture regulation.
What do we check on your vehicle?
We check sensor location, heating, exhaust leaks, mixture readings and catalyst condition. Suppression cannot repair an incorrect mixture or failed catalyst. 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.
