Good morning to all colleagues.
I am writing this technical information so that I can 'help' in case a similar problem arises.
The car in question arrives with AdBlue blockage is high ash load in the particulate filter.
After resetting the AdBlue system and regenerating and flushing the particulate filter (Fap wear parameters were still in tolerance) .
Error remains in diagnosis P242F-97 with particulate filter description. (engine light off, the error is only present if a reading is taken using a diagnostics tester).
After seeing and checking the parameters and seeing that everything was in order, we came to the conclusion that it was a false error (Peugeot itself says through internal service that on a number of cars with a generous mileage this error occurs but is not to be taken as such) the vehicle in question has 180,000 km
I hope I can be of help to someone I greet and wish you a good day
