Tax probe on five Volkswagen workers the latest in emissions-cheating scandal

German prosecutors have widened their investigation of Volkswagen to include suspicions of tax evasion linked to the emissions-cheating scandal.

Prosecutor Birgit Seel said the probe was focused on five Volkswagen employees but did not release their names.

The focus of the investigation is on tax breaks Volkswagen received for producing low-polluting cars that it might not have qualified for if the emissions had been correctly reported, Ms Seel said.

Volkswagen has acknowledged it produced 11m vehicles worldwide with small diesel engines that contained software allowing them to cheat nitrogen oxide tests.

Earlier this month, the car maker also said that it found “unexplained inconsistencies” in carbon dioxide emissions from more of its vehicles.

Chief executive Matthias Mueller told company managers that all technical details on how to fix cars fitted with emissions rigging software in Europe would be provided to Germany’s Federal Motor Transport Authority by the end of November, and most would not require major work.

He said the agency has already signed off on a software update which will be enough to fix affected two-litre diesel motors, and has given the “basic go” to a fix for the 1.6-litre vehicles that will involve a software update and a “relatively simple” replacement of an air filter cartridge and grill.

Details are still being finalised on a fix for 1.2-litre motors, but it should also just require a software update.

Meanwhile, Volkswagen subsidiary Audi said it had agreed to revise and resubmit to US authorities the parameters of its engine-management software used in the V6 TDI three-litre engine, which is used in its American models A6, A7, A8, Q5 and Q7 from 2009 on.
