German Prosecutors Say 17 Suspects Now Targeted In Volkswagen Emissions Probe

Frankfurt, Germany : German prosecutors looking into the massive emissions-cheating scandal at auto giant Volkswagen said today that the number of suspects under investigation had increased from six to 17, but that no former or current board members are involved.

"The number of suspects in the investigation into the nitrogen oxide manipulation has increased from six to 17," chief prosecutor Klaus Ziehe told AFP.

"There no former or current board members among the suspects," he added.

VW is based in Wolfsburg in the regional state of Lower Saxony, so prosecutors in the nearby city of Brunswick are handling the case.

VW, a former paragon of German industry with ambitions to become the world's biggest carmaker, has been plunged into its deepest-ever crisis by revelations that it installed emissions-cheating software into 11 million diesel engines worldwide.

The software, known as a "defeat device", limits the output of toxic nitrogen oxides to US legal limits during emissions test by regulators.

But when the vehicles are in actual use, the software allows them to spew poisonous gases at up to 40 times the permitted levels.

Nitrogen oxide is a pollutant associated with respiratory problems and defeat devices are prohibited in the United States, where the VW scam was originally exposed, as well as in other countries.

On top of still unquantifiable regulatory fines in a range of countries, VW is facing a slew of legal suits, notably in the US and Germany, from angry car owners, as well as from shareholders seeking damages for the massive loss in the value of their shares since September.

'Small Group Of Culprits'

VW has insisted from the very beginning that a small group of engineers was behind the scam. A number of managers have been suspended or sacked since the affair came to light, including the head of research and development at VW's upmarket brand, Audi.

But in a copy of the defence document obtained by AFP, VW's lawyers have sought to exonerate the group's management in the affair, including former chief executive Martin Winterkorn and other board members, such as current supervisory board chief Hans Dieter Poetsch.

It conceded that discussions had been held and memos exchanged at top management level, but the issue was simply one of a number of others for board members.

Winterkorn, who resigned in the wake of the affair, may have been warned as early as May 2014 of possible anomalies dogging its diesel engines, 16 months before the scandal erupted worldwide, the company admitted.

However, none of its top bosses could have known of the full extent of the scandal until it broke in September 2015, VW argued.

At a workers' meeting in Wolfsburg on Tuesday, the group's new chief executive Matthias Mueller rejected accusations of management attempts at a cover-up or foot-dragging in the probe.

The investigation to find the culprits was "ruthless," he insisted.

"The software manipulation and its consequences will be with us for a long time to come," Mueller said. But "2016 will be the year during which we aim to solve to problem with our diesel engines for our customers," the CEO continued.

"A number of questions can only be cleared up in the next years.

These include the financial consequences, which cannot yet be fully gauged as yet. But they will be substantial and painful," Mueller said.
