Australian motorists attended the Federal Court today against the global carmaker Volkswagen, as it has been three years since their cars were revealed to have been fitted with software that could detect test conditions and reduce emissions in order to improve results.

The scandal led to the resignation of Volkswagen executives, saw others sentenced to jail and resulted in billions of dollars in fines.

Customers in Canada and the United States were compensated, but the Australian wing of the company insisted they had no case to answer and hasn't offered compensation to Australian drivers.
