German authorities ask Porsche to recall 22,000 Cayenne SUVs in Europe after discovering what are believed to be illegal 'defeat devices'

German authorities have found an emissions ‘defeat device’ in the Porsche Cayenne, leading to a recall of 22,000 cars. The model affected is the 3.0-litre turbodiesel that is still in production and available in the UK.

The German transport minister, Alexander Dobrindt said authorities will order Porsche to issue an obligatory recall for 22,000 Cayennes registered across Europe. Though 7,500 of these cars have been confirmed to be registered in Germany, UK figures have yet to be published.

The device was found after tests carried out by transport authorities in Germany. A ‘warm-up strategy’ is triggered when cars are being tested which limits emissions of nitrogen oxide. Emissions are much higher when the car is on the road.

Dobrindt said: “There is no explanation as to why this software is in this car.” The minister went on to explain that because the Cayenne comes with a modern emissions system that's capable of meeting the emissions standards, Porsche should be able to produce a modified software system quickly.

Talks with the manufacturer also raised suspicions there may be similar software in a Volkswagen Touareg three-litre diesel, but authorities have yet to carry out tests on it.

VW's 3.0-litre diesel unit was found to violate US emissions standards earlier last year, with the VW Group ordered to either fix or pay owners of the 80,000 vehicles compensation.
