Amendments to the formal proposal for Amendment 3 to GTR 19 introducing new OBD provisions pursuant to the Phase 2 development of the GTR 15 WLTP emissions regulation. This document proposed during the 80th GRPE is also available in .docx format and in pdf format with the track changes showing the modifications.

The Technical Report to amendment 3 gives the background to the amendment that proposes the need to modify the scope and to add procedures and requirements on Conformity of Production (CoP) as an Optional Annex. The amendment also replaces the previous cross-references to technical requirements in UN Regulation No.83 07 series with the full text of those requirements to align with UN regulation on WLTP.
