A fire at a supplier is affecting some Audi output this week.
Reuters reported A4 and A5 production at Ingolstadt is off until Thursday due to the parts shortage.
Audi produces 1,400 of the cars per day at the plant, its largest, so will lose 5,600 vehicles this week. A fire at a supplier making firewall insulation had disrupted parts deliveries, a spokeswoman told Reuters on Monday.
About 8,500 of the 43,000 workers Audi employed at the plant would be affected and not working Monday to Thursday, she added.
Production of additional A4 and A5 cars at Neckarsulm had not been affected.
