OREANDA-NEWS. Only three weeks after implementation of the technical measures for EA189 engines affected by the NOx issue commenced the Volkswagen Group has already successfully completed modification of over 50 percent of the first wave in Germany. By Thursday, new engine control software had been installed in some 4,300 Volkswagen Amarok. The vehicle now meets the limits required to comply with the EU5 emissions standard.

In December 2015, the Volkswagen Group presented specific technical measures to the Germen Federal Motor Transport Authority (KBA) for the EA189 engines affected by the NOx issue. As agreed, Volkswagen began implementing the measures at the end of January for engines with a capacity of 2.0 liters.

Over the next few months, the measures will also be implemented on engines with 1.2 and 1.6-liter capacities. Volkswagen started with the Amarok at the end of January. The Volkswagen Passat with the affected 2.0-liter engines will follow in March. Modification of the 1.2-liter engines is scheduled for the end of the second quarter. Completing the recall, the measures for vehicles with a 1.6-liter engine will be carried out from the third quarter of 2016.

A software update is planned for the 1.2-liter, 1.6-liter and 2.0-liter EA189 engines. The pure labor time for this will be less than half an hour, as has been confirmed by the measures carried out on the Amarok. For the 1.6-liter engine a flow rectifier will additionally be fitted to the intake duct with the expected labor time, inclusive of software update, of just under 45 minutes.
