These systems are struggling to work correctly particularly with urban cycle running.
You will see many with display warning on but the parameters seem OK.
Check the recommended replacement interval and if close to it consider replacement.
If you have fooled the car by re setting particle filter soot to zero and also checked the additive ecu and reset the counter to zero then ask the customer to now monitor the car.
If you get display message back within a couple of weeks or even months then filter required because the cerine fluid gets baked onto the filter element(regen only burning soot away).
