In a press statement, François Bausch said that the Audi A7 models, equipped with a V6 TDI engine and the AL551 gearbox, and the Audi A8 (EURO5), equipped with a V8 TDI engine and the gearbox AL951, built between 2009 and 2013, were fitted with the defeat device.

Bausch cites tests conducted by Germany’s automobile federation KBA as the source of the information, which he says he learned of during an International Transport Forum Summit from 31 May to 2 June.

The KBA has called for affected vehicles to be recalled and adapted so that they conform to emissions standards.

“It goes without saying that the ministry for sustainable development and infrastructure (in Luxembourg) will support any recall action by the car dealer,” Bausch said. Luxembourg lodged a complaint in February 2017 over the diesel scandal.

Luxembourg’s vehicle control authority says it was duped into issuing approval certificates for vehicles affected by the scandal because test results were distorted by the defeat device.
