German prosecutors have widened a probe into suspected market manipulation by managers at Volkswagen (VOWG_p.DE) to include the carmaker’s supervisory board Chairman Hans Dieter Poetsch, VW said on Sunday.
 The investigation, which relates to Poetsch’s time as finance chief of VW, is the latest fallout from the carmaker’s admission last year that it cheated on diesel emissions tests.
 VW has admitted that it installed software that deactivated pollution controls on more than 11 million diesel vehicles sold worldwide, rattling its global business, damaging its reputation and prompting the departure of Chief Executive Martin Winterkorn.
