FRANKFURT: A German court ruled Wednesday that software updates meant to fix the “dieselgate” emissions cheating in certain Volkswagen models were themselves illegal, dealing another blow to the auto giant.

The ruling marks a victory for German environmental group DUH which had brought the case against the KBA federal transport authority.

The Schleswig-Holstein administrative court agreed with the DUH that the KBA regulator should not have approved the software fixes in 62 diesel models with EA-189 engines across VW’s own brand and its Seat and Audi subsidiaries.
