Mercedes V Klasse incomplete system readiness check

The incomplete system readiness check after OBD2 diagnostics on your 2007 Mercedes V Klasse suggests the drive cycle required for emissions test readiness might not have been completed. Have you ensured all monitors have run since the diagnostic check? Which monitors are incomplete?

How do I determine which specific monitors are incomplete on the V Klasse? Is a computer reset required, or is there a specific procedure?

To determine the status of individual monitors, a car diagnostics tool capable of reading OBD2 data is necessary. The tool will display which monitors within the exhaust system, such as catalyst, oxygen sensor, or evaporative system, are not ready. A computer reset might clear the error, but the underlying issue preventing readiness will persist. Completing the drive cycle is essential before a vehicle inspection.

The issue was resolved by performing a specific drive cycle as you suggested. No parts replacement or reset was necessary. The emissions test now passes. Thank you for the clarification. Total repair cost: 0€.
