Porsche Cayenne Diesel sales halted amid diesel scandal
EPA notice alleges V6 diesel engines possess emissions-cheating technology
Porsche has issued a stop-sale order for the 2014 through 2016 model year Cayenne Diesel, with Audi halting sales of a number of its models that also use the 3.0-liter TDI engine, Automotive News reports. The Cayenne SUV is one of several Volkswagen, Audi and Porsche models that were named by the EPA in a Notice of Violation (NOV) that was made public on Monday, Nov. 2, that drew a prompt rebuff from Volkswagen AG and Porsche.
The Cayenne Diesel has been on the market for two years, and uses the 3.0-liter TDI engine that was cited by the EPA as also containing a “defeat device” which allegedly disables parts of the emissions control system when the vehicle is not in testing mode.
“We are surprised to learn this information. Until this notice, all of our information was that the Porsche Cayenne Diesel is fully compliant,” Porsche Cars North America wrote in a statement on Tuesday, Nov. 3.
In all, some 10,000 models from across Audi and Porsche brands are believed to be affected, based on the statements provided by the EPA in their Notice of Violation. The EPA has only implicated the 2015 model year Cayenne Diesel in the document outlining the alleged presence of emissions-cheating software which the agency said operates in a manner similar to the devices found in 2.0-liter TDI diesel engines in Volkswagen and Audi models.
The automaker is not recalling the named Porsche Diesel models, and has stated that it plans to cooperate with the EPA in the investigation.
“We are working intensively to resolve this matter as soon as possible. Customers may continue to operate their vehicles normally,” Porsche said in a statement.
Other models named by the EPA in the document alleging the presence of defeat devices include the 2014 Volkswagen Touareg, 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 crossover. Audi has announced that it is halting sales of those models, including the 2013-2015 Q7 SUV, though the company is not planning a recall at this time.
The announcement by the EPA came as a surprise to VW AG, which has indicated that it had tested other diesel engines in its lineup and found no discrepancy. Until the EPA announcement, it was believed by VW AG and regulators that only several versions of the 2.0-liter TDI engines contained the emissions-cheating software.
