The vehicle manufacturer shall take the necessary measures to ensure that the processes set up for the purposes of determining CO2 emissions and fuel consumption for all the vehicle groups covered by the licence granted pursuant to Article 7 or the extension to the licence pursuant to Article 8(1) continue to be adequate for that purpose.\nThe vehicle manufacturer shall, on a yearly basis, perform the verification testing procedure set out in Annex Xa on a minimum number of vehicles in accordance with point 3 of that Annex.

The approval authority shall perform, four times per year, an assessment as referred to in point 2 of Annex II in order to verify if the processes set up by the manufacturer for the purposes of determining CO2 emissions and fuel consumption for all the vehicle groups covered by the licence continue to be adequate. The assessment shall also include verification of the selection of the input information and input data and repetition of the simulations performed by the manufacturer,\nWhere a vehicle fails the verification testing procedure set out in Annex Xa, the approval authority shall start an investigation to determine the cause of that failure, in accordance with Annex Xa. ...\nIf the cause of the failure is linked to the operation of the simulation tool, Article 21 shall apply. If the cause of the failure is linked to the certified CO 2 emissions and fuel consumption related properties of components, separate technical units and systems, Article 23 shall apply.\n...",
