Function, changes and requirements
What does the option mean?
The option concerns actuator control or monitoring, not an automatic power increase. Altering it may affect other engine functions.
What do we check on your vehicle?
We check commanded and actual position, deposits, mechanics, wiring and the specific purpose of the valve. 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.
