BERLIN -- Production is back to normal across all Volkswagen Group brands and regions, a company spokesperson said on Friday after an IT outage earlier this week caused most of its German plants to halt production.
"Individual systems may still be affected in a transitional phase," the spokesperson said.
VW’s global production network was up and running again on Thursday after the incident, which VW said began early on Wednesday, impacted the entire group, which includes the Porsche brand and Audi, highlighting the vulnerability of network infrastructure at the automaker.
The company said it was unlikely that an external attack was the cause of the outage.
At the time, VW said an unspecified "IT malfunction of network components" hit its global headquarters in Wolfsburg, Germany, on Wednesday, halting production in the Wolfsburg production complex.
The outage also affected German vehicle plants in Emden, Osnabrueck, Hanover, Dresden and Zwickau, and component factories in Brunswick, Kassel, Chemnitz and Salzgitter.
An Audi spokesperson said on Wednesday that its production had been impacted. Porsche had no immediate comment.
In August, Toyota was forced to halt output at 14 Japanese plants after a computer system processing orders for vehicle parts broke down.
