The review is being handled by Agency Insight and run by Hugh Fletcher, the national digital manager for Audi UK.
Razorfish London, the incumbent on the account, is not repitching for the business. It will continue to work with Audi in Germany.
Bartle Bogle Hegarty, which handles Audi UK’s above-the-line advertising, is unaffected by the review.
An Audi spokeswoman said: "As part of an overall strategic review for 2013, which is focusing heavily on the growing importance of digital marketing, Audi UK is conducting a digital pitch for a new web and strategic digital partner."
Audi has not disclosed details of when the pitch process will conclude.
Recent digital work from Audi includes a digital showroom in Piccadilly Circus, devised by Razorfish, and an iPad app for the Le Mans 24-hour race, developed by the mobile agency Somo.
