Swiss report on circumvention of pollution-control systems through the use of aftermarket AdBlue emulators that stop AdBlue injection while preventing detection of the failure by the engine management system.

23. The expert from Switzerland presented GRPE-75-06 on manipulations on EURO V and VI trucks by aftermarket suppression of AdBlue injection. He explained that the Swiss Authorities had decided to act after some previous cases in other countries and that suspect vehicles had been immobilized and inspected. He mentioned that 100 manipulated vehicles had been discovered nationwide since February 2017. He underlined that only manipulated EURO V vehicles had been identified and no manipulated EURO VI vehicles had been detected so far due to the lack of access to the emission control software. He invited Contracting Parties to address the five questions listed in GRPE-75-06 in order to exchange information on manipulation detection methods and enforcement strategies. Following a question raised by the expert from Italy, he clarified that the registration documents of the manipulated trucks had not yet been used to contact corresponding authorities.

24. The expert from the European Automobile Manufacturers Association (ACEA) expressed his readiness to share with GRPE a study prepared by his organization on this topic including information on used devices and geographical spread.

25. The experts from Austria, Canada, France, Sweden and UK reported similar concerns and investigations in their respective countries and showed their interest to exchange views on this subject.

26. The Chair of GRPE invited all stakeholders to keep on sharing information on this important issue. He also invited the expert from Switzerland to bring this topic to WP.29 and to present an updated report at the next GRPE session in January 2018.
