Questions referred







1.


Must Article 2(6) of and Annex III, section 3.13.4 to Implementing Regulation (EC) No 692/2008 (1) (in conjunction with Article 3(10) of Regulation (EC) No 715/2007) (2) be interpreted as meaning that a pollution control device (control programme for the regeneration of the storage catalyst in the preparation cycle), which is deemed to be a continuously regenerating system because regeneration (cleaning process) occurs at least once per type I test, and the device has already regenerated at least once during the vehicle preparation cycle (Precon or preconditioning), is a defeat device within the meaning of Article 3(10) of Regulation No 715/2007?










2.








(a)


Must Article 5(2)(c) of Regulation No 715/2007 (in conjunction with Article 3(10) of that regulation and Article 2(6) of and Annex III, section 3.13.4 to Implementing Regulation No 692/2008) be interpreted as meaning that (if so) such a defeat device is permissible because the conditions are, in essence, included in the relevant emissions test procedure?










(b)


Must Article 5(1) of Regulation No 715/2007 (in conjunction with Article 3(10) of that regulation and Article 2(6) of and Annex III, section 3.13.4 to Implementing Regulation No 692/2008) be interpreted as meaning that (if so) such a defeat device is permissible if the emission-related operation it exhibits in the test procedure (approval test) is present in the majority of cases, even in normal use (in real-life operation)?














3.


Must paragraph 2.20. of and Annex 13, paragraph 3 to the UNECE Regulation (3) (in conjunction with Annex III, section 3.13.1 to and Article 2(6) of Implementing Regulation No 692/2008) be interpreted as meaning that the arrangement laid down in the second sentence of Annex 13, paragraph 3 to the UNECE Regulation, in accordance with which the switch (to prevent or permit the regeneration process) may be activated during preconditioning cycles only in order to prevent regeneration, applies only to the special test procedure provided for in Annex 13 to the UNECE Regulation and thus to the emissions testing of a vehicle with a periodically regenerating system and not also in respect of a vehicle with a continuously regenerating system?
