Volkswagens in Australia using more diesel after recall, research finds

Australian Automobile Association calls for real-world testing after finding nitrogen oxide emissions four times the levels observed in lab

Volkswagen cars in Australia are guzzling up to 14% more diesel fuel after a recall fix designed to cut emissions, research has found, reigniting calls for emissions to be tested in the real world rather than a laboratory.

The analysis, commissioned by the Australian Automobile Association, which is campaigning for real-world testing, examined affected VW cars before recall and immediately after.
