Volkswagen drivers say software fix causes problems
9 April 2017
Volkswagen’s emissions cheating scandal has taken another twist, with some drivers now telling the ABC the company’s software upgrade is causing problems with their cars. The upgrade is the only compensation on offer to Australian customers. More than 100 drivers have contacted the law firms running class actions against Volkswagen, complaining about a drop in fuel efficiency and performance after having the upgrade.
Translated from Dutch NOS TV:
With special software, emission tests were manipulated, says Minister Alexander Dobrindt. The models in question are said to actually emit twice the allowable amount of nitric oxide (Nox).
The Ministry will give Audi up to 12 June the opportunity to come up with a viable solution to the diesel fraud. The car manufacturer says that the software update will start in July. About 14,000 of these A7s and A8s were sold in Germany. It is unclear whether, and if so, how many have been sold in the Netherlands.
The charge had been expected for a while. In March, hundreds of detectives entered the Audi headquarters in Ingolstadt. Then it became apparent that several top managers of the Volkswagen group (where Audi is part of) are under suspicion.
Sister company Volkswagen has paid more than 22 billion euros for damages and settlements in the US due to ‘dieselgate‘. In 2016, the Süddeutsche Zeitung daily claimed that Audi is the source of the fraudulent software scandal.
