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 of a deNOx system or a diesel particulate filter;

   (b)   a deNOx system, where fitted;

   (c)   a diesel particulate filter, where fitted;

   (d)   a combined deNOx-diesel particulate filter system.

 2.        From 1 October 2008 for new type-approvals and from 1 October 2009 for all type-approvals, a compression-ignition or a gas engine type-approved by reference to the emission limit values set out in row B2 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 OBD system that signals the presence of a fault to the driver if the OBD threshold limits set out in row B2 or row C of the table in paragraph 3 are exceeded.

 The OBD system shall also include an interface between the engine electronic control unit (EECU) and any other engine or vehicle electrical or electronic systems that provide an input to or receive an output from the EECU and which affect the correct functioning of the emission control system, such as the interface between the EECU and a transmission electronic control unit.

   3.        The OBD threshold limits shall be as follows:

                                                  Compression-ignition engines
 Row
    Mass of oxides of nitrogen (NOx) g/kWh     Mass of particulate (PT) g/kWh
 B1 (2005)                                  7,0                                 0,1
 B2 (2008)                                  7,0                                 0,1
 C (EEV)                                    7,0                                 0,1

 4.        Full and uniform access to OBD information must be provided for the purposes of testing, diagnosis, servicing and repair in keeping with the relevant provisions of Directive 70/220/EEC and provisions regarding replacement components ensuring compatibility with OBD systems.

 5.        The measures for the implementation of paragraphs 1, 2 and 3 shall be adopted by 28 December 2005 at the latest.

   Article 5

   Emission control systems using consumable reagents

 In defining the measures necessary to implement Article 4, as provided for by Article 7(1), the Commission shall, if appropriate, include technical measures to minimise the risk of emission control systems using consumable reagents being inadequately maintained in service. In addition, and if appropriate, measures shall be included to ensure that emissions of ammonia due to the use of consumable reagents are minimised.

   Article 6

   Tax incentives

  1.     Member States may make provision for tax incentives only in respect of vehicles which comply with this Directive. Such incentives shall comply with the provisions of the Treaty, as well as with either paragraph 2 or paragraph 3 of this Article.

 2.        The incentives shall apply to all new vehicles offered for   sale on
