Porsche recalls 22,000 Cayenne models

Porsche Cayenne models with 3-litre diesel engines have been recalled by German Transport Minister Alexander Dobrindt after potentially illegal emissions-controlling software in the vehicles was found. Dobrindt told reporters he was withdrawing certification for the vehicles, which will need to undergo a software update. Sports car maker Porsche AG is owned by Volkswagen, which in 2015 admitted to systematic manipulation of engine management software to cheat emissions tests. Porsche said it had discovered 'irregular' engine management software during an internal probe into emissions. Porsche also said it had agreed to recall the vehicles to fix the problem.
