VW urged to come clean over which UK diesel vehicles are affected

Lawyers acting for Volkswagen drivers in UK attack 'lack of clarity' as UK prime minister calls company's actions unacceptable

Lawyers for UK drivers have urged Volkswagen to "come clean" over exactly which cars have been affected in Britain by the emissions-rigging scandal that has rocked the global car industry.

The call came as the UK prime minister, David Cameron, labelled VW's action as "unacceptable", and German newspapers claimed the company had been aware of the cheating several years ago. At its near-10-hour meeting in Wolfsburg on Friday, the company's 20-member board discussed an internal report that showed an employee warned in 2011 about the illegal use of software for emissions tests, according to the Conservative daily Frankfurter Allgemeine Zeitung, citing sources close to the board. Bild reported that Bosch, which supplied the software for test purposes in 2007, warned about its planned illegal use at the time.
