Special function PN019 allows the user to perform changes to various coding parameters in the modules of PSA vehicles including 2021 models. This allows the user to both to change current configuration parameters but also to perform retrofits in the vehicle and coding them as though they were originally fitted to the car in question.
N.B. Please note that you will require an AVDI interface with an active AMS in order to use this special function. No tokens are required.
