Volkswagen and Porsche have announced a safety recall of 800,000 vehicles worldwide due to a suspected problem with the pedals.

Internal checks found that a fastener in the pedal system could become loose, the Volkswagen Group brands said in an alert.

Porsche and Volkswagen models from 2011 to 2016 are being recalled.

Both brands said they would contact owners to arrange when to take their vehicles in for a service to resolve the issue.

It will take less than half an hour to fix, they said.

VW Group admitted in September that 482,000 diesel vehicles in the US were fitted with defeat device software to switch engines to a cleaner mode when they were being tested.

But despite the German-based manufacturer also announcing that some 11 million vehicles were affected worldwide - including almost 1.2 million in the UK - it is insisting that it did not break European rules on testing.
