Interstar system readiness check issue

I had a similar issue with my 2018 Peugeot 308 after running diagnostics. The system readiness wasn't completing. Was anything reset or cleared during the OBD2 session?

Thanks. Yes, I did clear some historic fault codes. Could that be why the system readiness check is failing?

Yes, clearing codes will reset the readiness monitors. They need to run and complete again. However, if it persists, a workshop visit might be needed to check for underlying issues.

Thanks! It turned out to be exactly as you described. The system readiness reset after driving for a while. No repair was necessary, so the cost was 0€.
