Udinese bought 50% of his contract in January 2006 for €1 million and he remained at Empoli until the summer. During the 2006–07 season, Coda had to contend with a place on the bench but he eventually earned a place in the starting eleven by the second half of the season. In June 2007, Udinese acquired the remainder of his contract for €1.315 million. By the 2008–09 season, he became first choice, often partnering Maurizio Domizzi, and made his European debut in September 2008 in the UEFA Cup. In March 2010, he was ruled out for the rest of the season after injuring his knee just barely five minutes into the match against Chievo Verona and had to be substituted.
