Primera System Readiness Check Incomplete

I also drive a Primera and had a similar problem. Was the engine light on before you scanned it, or did it appear afterward? Clearing codes can mess with the readiness monitors, and they take a while to reset. How many drive cycles since the scan?

The engine light was on before the OBD2 scan. I've completed about three drive cycles since clearing the codes. Could that be why the system readiness check is incomplete? What do you suggest?

Yes, three drive cycles might not be enough. It can take five to ten cycles for the readiness monitors to complete. If the error is still there after that, I'd visit a workshop. They have the equipment to check what's going on.

I kept driving the vehicle, and after about seven drive cycles, the system readiness check completed, and the error message disappeared. The diagnostics readout confirms the error doesn't come up again. The repair cost was 0€. Thanks for the guidance.
