FRANKFURT (Reuters) - Luxury car maker Audi (>> Audi AG) has launched a recall for up to 850,000 diesel-fueled cars to update vehicle software controlling emissions in a bid to avoid potential driving bans, it said on Friday.

The service is also being offered to Porsche- and Volkswagen- branded cars using the same six- and eight-cylinder engines, Audi said.

The German government and car industry have agreed on a diesel rescue plan to be presented early August, industry and political sources told Reuters earlier on Friday.
