What does the system do?
An ECU stores a diagnostic trouble code when a monitored condition is implausible. Status, freeze-frame data and measurements help identify the cause.

Function, changes and requirements
What does the option mean?
This option concerns specifically identified codes. Altering their monitoring differs from clearing stored faults once; hiding a message does not remove the defect.
What do we check on your vehicle?
We need the complete code, ECU, occurrence conditions and modification history. Safety and emissions monitoring require particular care. 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.
