Volkswagen emissions glitch were behind the brand’s recall letters from April image

This year in April, Volkswagen of America told the owners of diesel powered Audi and Volkswagen models they should get their cars to a dealer to install a new software so emissions would be optimized and operate efficiently.

The company did not mention that the action was a result of government regulators that were dissatisfied with the reasons behind the difference between the laboratory emissions test results of the VW diesel cars and real life pollution.

The German carmaker started a recall in 2014 over a period of months after the officials at the California Air Resources Board and the EPA agreed in December the previous year to allow the voluntary fixing of what Volkswagen insisted to have been a technical malfunction

Dave Clegern, California Air Resources Board spokesman, confirmed on Wednesday that the letters were part of that recall. He stated that “This is one of the fixes they presented to us as a potential solution. It didn’t work”. VW did not comment on the letter.

The letter specified that: “if the [light] illuminates for any reason, your vehicle will not pass IM emissions inspection in some regions,” not mentioning the fact that California required the update before it would renew vehicle registrations. The letter also said that “The vehicle’s engine management software has been improved to assure your vehicle’s tailpipe emissions are optimized and operating efficiently”.

Last week the problem got public after the car manufacturer admitted it deliberately deceived the officials about the pollution caused by its diesel cars. The recall letter advised the owners of Volkswagen vehicles with 2-liter diesel engines, produced between 2010 and 2014 to go to the dealers for a software update that would fix a malfunction of the indicator light illuminating.
