before the start of the type-approval process.

              The approval authority shall make a preliminary assessment on the basis of the draft AES documentation package provided by the manufacturer. The approval authority shall make the preliminary assessment in accordance with the methodology described in Appendix 2 to Annex 10. The approval authority may deviate from that methodology in exceptional and duly justified cases.

              The preliminary assessment of the AES for new vehicle types shall remain valid for the purposes of type approval for a period of 18 months. That period may be extended by a further 12 months if the manufacturer provides the approval authority with proof that no new technologies have become available on the market that would change the preliminary assessment of the AES.

              3.1.4. In addition to the information referred to in paragraph 3.1.3., the manufacturer shall submit the following information:

                  (a) In the case of positive-ignition engines, a declaration by the manufacturer of the minimum percentage of misfires out of a total number of firing events that either would result in emissions exceeding the limits set out in Annex 9A if that percentage of misfire had been present from the start of the emission test as set out in Annex 4 or could lead to an exhaust catalyst, or catalysts, overheating prior to causing irreversible damage;

                  (b) A description of the provisions taken to prevent tampering with and modification of the emission control computer(s), including the facility for updating using a manufacturer-approved programme or calibration;

                  (c) Documentation of the OBD system, in accordance with the requirements set out in paragraph 8. of Annex 9B;

                  (d) OBD related information for the purpose of access to OBD, in accordance with the requirements of Annex 14 of this Regulation;

                  (e) A Statement of off-cycle emission compliance, with the requirements of paragraph 5.1.3. and paragraph 10. of Annex 10;

                  (f) A Statement of OBD in-use performance compliance, with the requirements of Appendix 2 to Annex 9A;

                  (g) The initial plan for in-service testing according to paragraph 2.4. of Annex 8;

                   (h) Where appropriate, copies of other type approvals with the relevant data to enable extension of approvals and establishment of deterioration factors;

                  (i) Where appropriate, the documentation packages required by this Regulation for the correct installation of the engine type-approved as separate technical unit

              3.1.5. The manufacturer shall submit to the technical service responsible for the type approval tests an engine or, as appropriate, a parent engine representative of the type to be approved.

              3.1.6. Changes to the make of a system, component or separate technical unit that occur after a type approval shall not automatically invalidate a type approval, unless its original characteristics or technical parameters are changed in such
