engine families or OBD engine families which are likely to be affected with the same defects. The need to amend the type approval documents shall be assessed by the manufacturer and the result reported to the Type Approval Authority.
9.3.3. The Type Approval Authority shall consult the manufacturer in order to secure agreement on a plan of remedial measures and on executing the plan. If the Type Approval Authority which granted the original type approval establishes that no agreement can be reached, it shall take the necessary measures, including, where necessary, the withdrawal of type approval, to ensure that production vehicles, systems, components or separate technical units, as the case may be, are brought into conformity with the approved type. The Type Approval Authority shall advise the Type Approval Authorities of the other contracting parties of the measures taken. If the type approval is withdrawn, the Type Approval Authority shall inform the Approval Authorities of the other contracting parties within 20 working days of the withdrawal and of the reasons therefor.
9.3.4. The Type Approval Authority shall within 30 working days from the date on which it has received the plan of remedial measures from the manufacturer, approve or reject the plan of remedial measures. The Type Approval Authority shall within the same time also notify the manufacturer and all Contracting Parties of its decision to approve or reject the plan of remedial measures.
9.3.5. The manufacturer shall be responsible for the execution of the approved plan of remedial measures.
9.3.6. The manufacturer shall keep a record of every engine system or vehicle recalled and repaired or modified and of the workshop which performed the repair. The Type Approval Authority shall have access to that record on request during the execution and for a period of 5 years after the completion of the execution of the plan.
9.3.7. Any repair or modification referred to in paragraph 9.3.6. shall be recorded in a certificate supplied by the manufacturer to the owner of the engine or vehicle.
