The Volkswagen Diesel Customer Forum is a 1,700-member Facebook group that recently voiced its concerns over the fixed cars' reliability and performance. Recently, three representatives from the group met with the United Kingdom's Transport Select Committee and disclosed newly developed issues in their VW, Audi, Skoda and Seat cars ranging from diesel particulate failure (DPF) to exhaust gas recirculation (EGR) problems, and vehicles entering limp home mode. There have also reportedly been turbo and injector failures. A 41-page report was released, detailing problems with the affected cars.
Volkswagen, however, told Autocar that there have now been 600,000 cars modified with the approved emissions fix procedures at a rate of roughly 20,000 cars a week, and that less than 6,000 cars overall have experienced problems. As Volkswagen's representative said, "That means that over 99 percent of customers are satisfied with the application of the technical measures, which of course are carried out free of charge. As you would expect, we make it a priority to look at the vehicles of the very small proportion of customers who report any issues."
In general, Volkswagen believes that issues have arised from improper maintenance and in some cases DPF deletion, and that they are not related to the EA189 engine's Dieselgate fix. VW maintains that the modifications do not have a negative effect on the cars. The VDCF, in the other hand, believes that these issues have not been properly logged by Volkswagen.
