The activity uses 'postscribed ID' technology, which allows brands to personalise mass-produced DVDs with geographical and personal information linked to postcodes. The technology is already used in countries including Germany.
The disks include multi-media content such as TV ads and a driver's-eye view of a test-drive. Recipients will be able to automatically confirm their data, request a printed brochure and book a test-drive at an Audi dealer.
Embedded technology also allows Audi to monitor when consumers view the disk, how often they look at it and when they switch off.
Royal Mail is promoting the disks to brands as part of its fightback against online direct-response marketing.
Audi tested the technology during December's launch of its Q7 model with a campaign by Bartle Bogle Hegarty.
