VW Says Some Diesels May Still Have Cheater Software

Volkswagen AG has advised Germany’s transport authority (KBA) that half a million diesels it recalled because they were rigged to cheat on emission tests may still do so after repairs, the Financial Times reports.

The problem could allow the engines to emit excessive levels of nitrogen oxides shortly after startup, according to the report. VW says the issue affects 500,000 of the 1.2-liter version of its “EA-189” engines, about 32,000 of which are in Germany.

VW recalled nearly 7 million diesels in Europe two years ago to update their emission control software.

Sources tell FT the issue was discovered last week but won’t be fully investigated until early January because of the Christmas and New Year holidays. In the meantime, it isn’t clear whether KBA will rule the software glitch a minor technical issue or declare it an illegal defeat device and demand a new recall.
