      Durability of emission control systems

  1.     From 1 October 2005 for new type-approvals and from 1 October 2006 for all type-approvals, the manufacturer shall demonstrate that a compression-ignition or gas engine type- approved by reference to the limit values set out in row B1 or row B2 or row C of the tables in Section 6.2.1 of Annex I will comply with those limit values for a useful life of:

   (a)   100 000 km or five years, whichever is the sooner, in the    case of engines to be fitted to vehicles of category N1 and M2;

   (b)   200 000 km or six years, whichever is the sooner, in the case of engines to be fitted to vehicles of category N2, N3  with a maximum technically permissible mass not exceeding 16 tonnes and M3 Class I, Class II and Class A, and Class B with a maximum technically permissible mass not exceeding 7,5 tonnes;

 From 1 October 2005, for new types, and from 1 October 2006, for all types, type-approvals granted to vehicles shall also require confirmation of the correct operation of the emission control devices during the normal life of the vehicle under normal conditions of use (conformity of in-service vehicles properly maintained and used).

  1.     From 1 October 2005 for new type-approvals of vehicles and from 1 October 2006 for all type-approvals, a compression-ignition engine type-approved by reference to the emission limit values set out in row B1 or row C of the tables in Section 6.2.1 of Annex I or a vehicle propelled by such an engine shall be fitted with an on-board diagnostic (OBD) system that signals the presence of a fault to the driver if the OBD threshold limits set out in row B1 or row C of the table in paragraph 3 are exceeded.

 In the case of exhaust after-treatment systems, the OBD system may monitor for major functional failure any of the following:

   (a)   a catalyst, where fitted as a separate unit, whether or not it is part
