SpaceTourer emissions error after OBD2 use

I have a SpaceTourer too, and something similar happened after using an OBD2 reader. The system readiness check confirms that all the onboard diagnostic systems are working, and the car is ready for an emissions test. The OBD2 thing probably reset some parameters. Did the error come right after the OBD2 reading?

Yes, the error appeared immediately after using the OBD2 reader. So, if it's a reset parameter issue, is there a way to fix it myself, or does it require specialized equipment?

It's likely the OBD2 wiped the readiness flags. Usually, the car needs to go through a specific 'drive cycle' to reset them – basically, a set pattern of driving conditions. But honestly, I just took mine to a workshop. They reset the system properly. It's a common problem and shouldn't cost anything.

I took it to the workshop as you suggested. They confirmed the OBD2 reading had reset the system readiness, and they reset everything. The repair cost was 0€. The error is now gone. Appreciate the help!
