What does the system do?
The EVAP system retains petrol vapours and meters them into the engine under suitable conditions. Canister, valve, lines and leak monitoring work together.

Function, changes and requirements
What does the option mean?
The option concerns control and monitoring. It does not repair a leaking tank or failed purge valve and can affect vapour emissions and engine running.
What do we check on your vehicle?
We check leaks, hose routing, valve operation and mixture correction. Fuel smells need an actual fault assessment. 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.
