VW’s relatively simple technical fixes for cheating 1.6 and 2.0L diesels accepted by KBA; 1.2L fix coming by end of month
The Volkswagen Group has proposed the specific technical fixes for the non-compliant 1.6-liter and 2.0-liter diesel EA 189 engines equipped with the software defeat device resulting in excessive NOxemissions to the German Federal Motor Transport Authority (Kraftfahrtbundesamt, KBA). Following an examination, these measures have been ratified by the KBA. (The remedies announced by Volkswagen AG apply only to affected TDI vehicles in Europe, and not to affected TDI vehicles in the United States and Canada.)
For the 1.6-liter diesel, a “flow transformer” will be fitted directly in front of the air mass sensor. This mesh will calm the swirled air flow in front of the air mass sensor and thus improving the measuring accuracy of the air mass sensor. The air mass sensor determines the current air mass throughput—a very important parameter for the engine management for an optimum combustion process.
In addition, a software update will be performed on this engine. The time needed for the implementation of the technical measures is expected to be less than one hour.
The 2.0 liter engines will get a software update. The pure labor time for this measure will be around half an hour.
Volkswagen says that after implementation of the technical measures, the vehicles will comply with the applicable emissions standards.
The final technical solution for the 1.2-liter diesel engine will be presented to the Federal Motor Transport Authority at the end of the month and is expected to comprise a software update.
Volkswagen said that due to advances in engine development and improved simulation of currents inside complex air intake systems, in combination with software optimization geared towards this, it was possible to produce a relatively simple and customer-friendly measure.
The objective for the development of the technical measures was to achieve the applicable emission targets in each case without any adverse effects on the engine output, fuel consumption and performance. However, as all model variants first have to be measured, Volkswagen cannot yet confirm that.
Based on these technical measures accepted by the Federal Motor Transport Authority, the necessary service concepts are currently being developed for the EU28 markets concerned. The aim is to implement the required technical update in the first vehicles during a recall from January 2016. According to the current assessment, all measures in the course of the recall for all engine variants will extend over the whole calendar year 2016.
Volkswagen will ensure that the time needed to implement the technical measures is as short as possible for all customers. In addition, Volkswagen will contact all customers and endeavor to consider individual customer needs during the implementation of these measures to avoid any disadvantages for the customer such as possible curbing of their mobility. In connection with this, the Volkswagen brand will thus ensure that all customers are offered appropriate replacement mobility options free of charge.
Based on the approach of the Volkswagen brand, the Group’s other brands—Audi, SEAT, ŠKODA and Volkswagen Commercial Vehicles—are also planning corresponding measures for their affected vehicles.
In addition, until 31 December 2016, Volkswagen AG is expressly forgoing the right to plea on the grounds of statutes of limitations in respect of any warranty or guarantee claims due to the software installed in vehicles with EA 189 engines, as long as the rights to make any such claims have not already expired. Volkswagen customers will therefore not be disadvantaged by any waiting.
The affected vehicles remain technically safe and can therefore be driven on public roads without any limitation.
