Recall of 22,000 Porsche cars following emissions cheating allegations

The recall of 22,000 Porsche’s has been announced by Germany’s transport minister in order to remove what is believed to be illegal emissions-controlling software.

This comes after Porsche’s sister firm Volkswagen says it will refit almost a million more diesel cars in Germany.

Allegations about Porsche first emerged in German magazine Der Spiegel last month.

It said it was told by a source that the Porsche Cayenne had a "warm up mode" whose true purpose was to comply with emissions requirements.

It said tests showed that once the car was confronted with small bends or a slope it switched to a different mode and emissions were higher.
