Volkswagen Group begins EA189 diesel engine emission fixes in Europe; 2.0L Amarok first

In December 2015, the Volkswagen Group presented specific technical measures to the German Federal Motor Transport Authority (KBA) for the EA189 engines affected by the NOx issue. (Earlier post.) As agreed, the Group began implementing the measures in Germany at the end of January for 2.0L engines.

Volkswagen is starting with the Amarok (a mid-size pickup truck produced by Volkswagen Commercial Vehicles), with the Passat to follow shortly. The installation of the new engine control software means that the Amarok now meets the limits required to comply with the EU5 emissions standard. Over the next few months, the measures will also be implemented on the engines with 1.2- and 1.6-liter displacements.

The aim of Volkswagen has been to ensure that these measures do not result in a change to the fuel economy figures, performance figures or CO2 or noise emissions of the vehicles affected. In the case of the Amarok, the Federal Motor Transport Authority has confirmed that this objective has been fully achieved.

For efficient implementation the affected vehicle models have been put into several groups. Only once the KBA has checked and confirmed the proposed measures are the customers affected being contacted and informed about the recall. In a second letter the vehicle owners will be requested to arrange an appointment with a Volkswagen partner. The implementation of the measure will extend across the whole 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. For the 1.6-liter engine, a flow rectifier will additionally be fitted in the intake duct with expected labour time, inclusive of software update, of just under 45 minutes.

Following in a few weeks’ time, in addition to the variants of the Passat, will be other models with the affected 2.0 TDI engines as well. Modification of the 1.2-liter engines affected 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.

At the same time the implementation of the technical measures will commence in other European countries in agreement with the responsible authorities and in accordance with the national requirements.

In January in the US, the Group failed to receive approval for its submitted recall plan for 2-liter diesel passenger vehicles sold between 2009 and 2015 with the software defeat devices. (Earlier post.) Work continues on that front.

It's a darn shame that VW had to lie to skirt around the EPA issues and subsequent environmental laws in Europe. The Tier Rating Program by the EPA was enacted to cut emissions in diesel engines beginning in the 1994 and grandfathered in diesel up until 2015. Take a look at this article about the environmental impact of diesel engines with this article. http://capitalremanexchange.com/epa-emission-regulations-regarding-remanufactured-diesel-engines/ All of other manufacturers made strides to pony up to the laws however VW decided to put a buck over environmental concerns.
