Volkswagen's software subsidiary Cariad is causing new trouble. The start of software and models has been postponed again.

The problems affect VW, Audi and also Porsche. The cost targets for renovating the unit are radical, says Peter Bosch, boss of the unit. The company is trying to find a solution to the problems at the subsidiary, says Bosch. It is the first time in the history of Volkswagen that a software subsidiary has been in such trouble, he says.
