Audi admits emissions 'irregularities', halt A6/A7 deliveries

German luxury carmaker Audi

German luxury carmaker Audi yesterday said it had detected 'irregularities' in the emissions controls of recent A6/A7 models, prompting it to halt deliveries in the latest twist in the 'dieselgate' scandal dogging parent company Volkswagen.

The admission came after Germany’s transport ministry said it was investigating suspicions that the carmaker had installed a new 'illegal defeat device' in some 60,000 A6/A7 models worldwide, around half of which are driving on German roads. 

The revelations were first reported by news weekly Spiegel, which said mass recalls were 'highly likely'.
