SET S TUDY - A IMS Field tests with diesel and petrol vehicles in different Member States as well as laboratory tests Aims of the SET study: 1. Definition of suitable thresholds for PM-measurement and CO-measurement 2. Comparison of reading out OBD versus tailpipe emission test 3. Compiling a precise recommendation including a cost/benefit analysis for the European Commission to adjust the PTI directive

3. I MPLICATIONS OF A NEW EMISSION TEST

4. C ONCLUSION The SET study results clearly demonstrate, that emission controls for modern vehicles are maximally effective when: • Both methods – OBD and tailpipe testing – are combined • The thresholds are adjusted to the modern vehicle technology • PM: K-value for Diesel vehicle as of Euro 5: 0,2 m -1 • CO: Vol. % for Petrol vehicles as of Euro 4: 0,1 Vol. % high idle • For customers hardly any additional costs arise • The benefit for the environment and health is significantly.

NOx measurement for Diesel Euro 4/5/6 engine 23

NO X FUNCTIONAL TEST : 1 ST F IELD TEST CAMPAIGN • A functional test, based on NOx levels at IDLE and FAST IDLE, has been performed over 233 vehicles . • Vehicles are flagged because of faulty behaviour of recycling system • (EGR valves…) EU DIRECTIVE position about NOx : Test with conclusion / Test without conclusion “Possibilities for improving test cycles to match on-road conditions 120,0% should be closely examined in order 100,0% to develop future solutions, 96,1% 80,0% including the establishment of test methods for the measurement of 60,0% NOx levels and of limit values for 40,0% NOx emissions. “ 20,0% 3,9% 0,0% A+B Because IDLE values are not reliable enough due to non homogenous vehicle’s manufacturer strategies Valid test results cannot be considered in 4% of the use case.

NO X FUNCTIONAL TEST : 2 ST L AB . T EST CAMPAIGN (Q1 2015) Correlation between:  Homologation test  New PTI procedure functional test including Fast Idle & High RPM sequences based on tail pipe measurement (NOx) & EOBD dynamic values Valid PTI procedure allows to flag faulty vehicle behavior of their anti NOx mechanism Fast Idle + High RPM Homologation cycle Euro 4 Euro 5 Euro 6 Euro 6 +SCR Zero default EGR valve blocked open EGR valve blocked at 60 % closed EGR valve blocked at 80 % closed EGR valve blocked at 100 % closed
