FRANKFURT -- Volkswagen Group's brands including Porsche and Audi continued to lose sales in their German home market in November due to delivery bottlenecks caused by a new vehicle testing regime.
Overall German registrations fell by 9.9 percent to 272,674 last month, the KBA motor vehicle agency said on Tuesday.
All VW Group's brands suffered sales declines.
Porsche registrations plunged 55 percent and Audi sales fell 43 percent. Seat sales were down 19 percent, while VW brand's volume dropped 15 percent and Skoda registrations fell 3 percent.
VW has said a shortage of engineers led to it failing to get vehicles ready for the Worldwide harmonized Light vehicle Test Procedure (WLTP) introduced on Sept. 1 for new cars in the European Union.
VW brand sales chief Juergen Stackmann said last month that the automaker is tackling the bottlenecks and will be ready for an "end-of-the-year sprint" in Europe after November.
Most volume brands lost sales in November, registration data showed.
Nissan sales fell 47 percent, Peugeot's volume was down 43 percent and Renault registrations dropped by 28 percent. Toyota sales fell 4.9 percent.
Opel volume declined by 4.4 percent and Fiat was down 3.1 percent.
