Follow-up to reports of a new cheat device
Audi admits that the software inside its automatic gearboxes can distort emissions during testing, according to a report from Reuters.
The revelation follows up on a report last week from German newspaper Bild am Sonntag, which pointed out that Audi had another possible cheat device. Earlier this summer, officials at the California Air Resources Board reportedly discovered a cheat device in the automatic transmission of an older Audi vehicle. The device, activated based on the angle of the steering wheel, has been used on both gasoline and diesel Audi models sold in Europe, the report said.
Under testing conditions, the software tells the transmission to shift more rapidly and in a way that lowers emissions, reports Sueddeutsche Zeitung, citing a VW document.
“Adaptive shift programs can lead to incorrect and non-reproducible results,” when tested, VW told Reuters in response to the Sueddeutsche Zeitung report.
“Audi has explained the technical backgrounds of adaptive shift programs to the Federal Motor Vehicle Authority KBA and has made available technical information,” VW continued. The automaker says it will continue its talks with the German transportation authority.
By reducing the need to shift as often, adaptive transmission control systems are said to improve performance while boosting fuel efficiency. “In normal use, these adaptive systems support the driver by adjusting the gear-shifting points to best adapt to each driving situation,” VW added.
The new defeat device compounds Audi’s emissions woes. VW is still working on a solution for 85,000 Audi, Porsche, and VW vehicles with cheat devices. The automaker has submitted proposed fixes for vehicles with the 3.0-liter diesel engines, but unlike cars with its 2.0-liter diesel engines, a solution has yet to be finalized.
